Coin, Credit, and Crown

Money in Mar de Oro

System-neutral

Coins, scales, financial papers and trade goods overlooking a busy Mar de Oro sailing harbor.
Weights, papers, and metal: the quiet machinery of the Golden Sea.

A coin is never just a coin.

Its metal tells you what it should be worth. Its weight tells you whether that value can be trusted. Its face tells you who minted it. Its reverse may tell you where it was issued. Its date may tell you where somebody has been.

Sometimes the wrong coin on a tavern counter tells everyone in the room far too much about you.

The four Mar de Oro denominations, their values, and their typical uses
CoinValueTypical use
Copperbase unitFood, drink, market goods, small services
Silver10 copperWages, lodging, ordinary trade
Gold10 silverEquipment, contracts, substantial purchases
Platinum10 goldRare high-value specie, banks, treasuries, major commerce

1 platinum = 10 gold = 100 silver = 1,000 copper.

The arithmetic is simple. The world around it is not.

A Simpler Standard Than History

Real Age of Sail money could be bewilderingly complicated. A merchant might keep accounts in one unit while receiving payment in several different kinds of coin. Foreign specie could circulate beside local currency. Governments changed coin standards. Coins could be clipped, worn, debased, countermarked, recalled, or valued differently from port to port.

Mar de Oro deliberately compresses that complexity into a common 10-to-1 standard. The historical uncertainty survives through mint reputation, foreign coinage, bargaining, credit, political acceptance, and the circumstances of the market.

Money travels. Trust travels less easily.

Money Has a Face

Every major power strikes its own coinage. The denomination may be familiar, but its design is political.

An Albion gold coin carries Albion authority. A Valdegracian silver coin carries Valdegracian authority. Eisenmark, Volkharov, and the other powers mark their money with rulers, crowns, beasts, ships, state emblems, cities, or other recognized symbols.

A merchant does not merely receive a gold coin. They receive an Albion gold coin.

A Heller innkeeper may know perfectly well that the piece in front of them contains good gold. They may still turn it over twice before accepting it, because somebody may eventually ask where it came from.

Heller Coinage

Heller does not maintain a completely separate monetary standard. It uses the Valdegracian standard.

Coins struck for circulation in Heller retain Valdegracian authority on one face and bear the emblem of Heller on the reverse. They remain Valdegracian-standard coins, but they are unmistakably Heller.

Valdegracia on one side. Heller on the other.

Copper, silver, gold, and the much rarer platinum can all exist as Heller issues. They do not require separate exchange rates. A Heller silver is still worth one silver. A Valdegracian silver is still worth one silver. What differs is origin, familiarity, and sometimes acceptance.

Countermarks

Not every accepted coin needs to be melted and struck again. Older Valdegracian coins and certain approved foreign issues may bear an official Heller countermark, a small stamp punched directly into the metal.

The mark tells a merchant that the coin has been inspected or officially accepted for circulation. A trader might see the Heller treasury punch and put the coin straight into the till. An unfamiliar foreign issue may go onto the scales first.

The Four Metals

Copper: The Money of the Street

Copper is the smallest and most ordinary denomination. Meals, ale, street food, ferry fares, candles, tips, market purchases, and small services are naturally priced in copper.

It is also the most local form of money. Transporting and verifying large quantities of foreign copper is rarely worth the trouble. A merchant may accept a few foreign copper pieces without concern, but sacks of unfamiliar copper are another matter.

Silver: The Working Currency

For most people, silver is serious money. Sailors are paid in silver. Craftsmen quote wages in silver. Rooms, tools, ordinary clothing, provisions, ammunition, and common commercial goods often fall naturally into silver prices. A purse containing copper and silver looks ordinary. Military payrolls and merchant strongboxes contain enormous quantities of it.

Gold: Money That Travels

Gold represents substantial wealth: weapons, fine equipment, livestock, cargo purchases, officer salaries, ship repairs, commercial contracts, bribes, property, and government payments.

Gold also travels well. A reputable foreign gold coin can be weighed, inspected, and exchanged almost anywhere serious commerce takes place. That does not mean everyone will accept it at full face value. It means they know it has value.

Platinum: Known, Valuable, Awkward

Platinum exists as recognized coinage in Mar de Oro, but it is rare. Officially, one platinum is worth ten gold.

Banks, governments, great trading houses, military treasuries, and wealthy merchants understand platinum perfectly well. The average tavern keeper may not have enough money to make change, may not know the issue, or may simply refuse to tie up so much value in one coin.

The coin is valuable. The problem is converting that value into something useful.

Face Value and Exchange Value

The monetary standard is fixed. A sound Albion gold coin is still one gold. A Heller merchant does not decide that gold itself is worth six silver because the coin came from Albion.

What the merchant can decide is whether they want Albion coin, how easy it will be to spend again, and what inconvenience or risk they are taking by accepting it.

  • Is the coin genuine?
  • Is it full weight?
  • Is the mint trusted?
  • Is the issue familiar?
  • Can the merchant easily spend it again?
  • Will accepting it attract attention?

An Albion gold coin may be accepted at face value in a cosmopolitan Heller port. The same coin may be awkward near a military installation during a crisis with Albion. Twenty newly struck Albion naval-pay pieces in the purse of a Heller dockworker may be valuable for reasons that have nothing to do with exchange.

Coins Can Be Weighed

Serious merchants and money changers own scales. Coins made from valuable metal invite abuse. A person can remove tiny amounts of metal from an edge. A government can reduce the amount or purity of precious metal in a new issue. A heavily worn coin may simply contain less metal than it once did.

“It says one gold.”

The merchant points toward the scales.

“Then the king can buy it from you.”

The Money Changer

Every serious port has one. Most have several.

Money changers live in the gap between value and convenience. They weigh coins, recognize mints, identify old issues, test suspicious metal, exchange foreign currency, verify official stamps, deal in notes, and charge for doing it.

Ordinary Money

The coin is familiar, sound, and easy to spend. Exchange is near face value.

Awkward Money

The currency comes from a hostile power, distant mint, unpopular issue, or simply circulates poorly in the region. A changer may take roughly 10 percent.

Difficult Money

The issue is damaged, politically suspect, unusually rare, hard to verify, or inconvenient to move. The discount may reach 20 percent, or require negotiation.

Suspicious Money

Clipped, counterfeit-looking, unknown, or disputed money may have no standard exchange at all. It gets weighed, tested, and bargained over.

Bargaining

Not every price in Mar de Oro is fixed. Established shops, government offices, military suppliers, banks, and large trading houses often use formal prices. Markets, docks, auctions, cargo sales, private deals, smuggling, foreign exchange, and desperate wartime purchases are much more negotiable.

The listed price should normally be treated as the fair expected price. When negotiation actually matters, resolve it once.

A successful bargain usually shifts the price by about 10 percent. Strong leverage may justify 20 percent.

Failure normally means paying the original asking price, not receiving an arbitrary punishment. Use whatever social or negotiation mechanic the chosen rules system already provides.

  • Paying immediately
  • Using trusted local currency
  • Buying in quantity
  • Knowing the real market price
  • Having another seller available
  • Accepting politically awkward goods
  • Possessing valuable information
  • Offering a favor
  • Being a known customer

Trying to save two copper on dinner rarely deserves a roll. Trying to buy powder before dawn while an enemy squadron sits beyond the harbor mouth probably does.

The Coin Stays the Same. The Price Does Not.

A stable monetary standard does not mean prices are stable.

Bread may be cheap in a farming town and expensive on an isolated island. Powder becomes costly during war. Fresh water acquires a different value aboard a stranded ship. A blockade can turn ordinary provisions into luxuries.

This is not a change in the value of gold or silver. It is a change in the value of what people are trying to buy.

Scarcity, distance, harvests, shipping losses, monopoly, military demand, and desperation all move prices. For the GM, this means the 10-to-1 coin system can remain fixed while the economy still reacts naturally to events.

The Customs House Is Less Flexible

A tavern keeper may accept foreign gold. The tax collector does not have to.

Customs duties, harbor fees, licenses, fines, and official taxes may have to be paid in approved coin or recognized notes.

A Heller customs officer might accept Heller issues, standard Valdegracian coin, and properly stamped notes without question while sending unfamiliar foreign specie to an authorized exchange desk.

This gives governments quiet control over money and creates a useful distinction for travelers: possessing wealth and possessing usable wealth are not always the same thing.

Credit Is Money Too

Not every transaction ends with coins crossing a table.

Merchants extend credit. Shipowners maintain accounts. Captains acquire provisions against the reputation of their backers. Officers draw supplies against government authority. Trading houses advance funds against cargo that has not yet arrived.

A respected name can therefore be worth more than a heavy purse. A known Heller captain backed by a powerful merchant house may obtain repairs worth hundreds of gold with a signature. An unknown captain making the same promise may receive nothing.

Credit depends on trust.

A merchant who fails to honor obligations does not merely owe money. They may lose access to the network that allowed them to conduct business in the first place.

Bank Notes

Large amounts of wealth are inconvenient to carry as coin. They are heavy. They require guards. They attract thieves and privateers. They can sink.

Mar de Oro's great banks, governments, and merchant houses therefore issue notes representing monetary obligations. A bank note may promise that the bearer is entitled to receive a specified amount of money from the issuing institution.

The paper itself is worth almost nothing. The promise written on it may be worth a fortune.

The Official Stamp

A legitimate note carries marks of authority. These can include the issuing bank or treasury, denomination, date, signatures, registry or serial number, specialist paper, watermark, embossed seal, and an official treasury stamp.

The official stamp is particularly important in Mar de Oro. It tells the holder that a recognized institution stands behind the document.

PAY TO THE BEARER THE VALUE OF FIFTY GOLD COINS UPON PRESENTATION AT AN AUTHORIZED OFFICE OF THE ROYAL BANK OF VALDEGRACIA.

The stamp can make a piece of paper worth fifty gold. It can also make a convincing forgery dangerous enough to bring the full attention of the state.

Coins Cross Borders More Easily Than Promises

An Albion gold coin can be weighed. An Albion bank note cannot.

A Heller merchant may dislike Albion, distrust its government, and refuse Albion paper while still accepting an Albion gold coin after putting it on a scale.

Paper depends on confidence in the issuer. Does the bank exist? Is it solvent? Can the note actually be redeemed? Are the signatures and stamps genuine? Does anyone nearby deal with that institution?

A foreign coin may be inconvenient. A foreign promise may be worthless.

Heller Notes

Valdegracian financial instruments circulate throughout Heller. Documents formally processed or recognized through Heller institutions may also receive an official Heller stamp.

The stamp does not necessarily create a new currency. It certifies local recognition.

  • Valdegracian note with Heller stamp: familiar and immediately trusted.
  • Valdegracian note without Heller stamp: probably acceptable, but may warrant inspection.
  • Albion bank note: likely an exchange-house problem.

This mirrors Heller coinage. On metal, Valdegracia and Heller share the coin. On paper, the Heller stamp adds local authority to the promise.

Bills of Exchange

Not every financial document is intended to circulate like cash.

Merchants also use bills of exchange. A merchant may deposit funds with a banking house in one city and receive a document allowing payment to be collected through an associated house elsewhere.

In Stroomdijk, the Wisselbank handles letters of credit, currency exchange, commercial insurance, and clearing between states.

Instead of putting 2,000 gold aboard a ship, the merchant carries a document. At the destination, the bill is presented, the names and signatures are checked, the accounts are settled, and the money moves without the gold necessarily making the same journey.

Pay and Prize

People go to sea for many reasons. Money is one of them.

Sailors may receive advances before departure. Wages accumulate during long voyages. Military payrolls arrive late. Captains borrow against future earnings. Outfitters extend credit. Merchants finance expeditions in return for a share of the result.

Then there is prize money.

A successful capture can produce more money in a day than a sailor might otherwise earn in months. That does not mean the crew divides a chest equally on deck. Governments, owners, captains, officers, investors, creditors, and crews may all have claims.

A captured vessel must be valued. Its cargo must be inventoried. Legal ownership may need to be established. Debts may be settled first. By the time the money reaches an ordinary sailor, many hands may already have touched the account.

That does little to reduce the dream.

Who May Strike a Coin?

Putting an emblem on money is not merely decoration.

The authority to mint, approve, or countermark coinage is a political privilege. A ruler's image, a treasury stamp, or a ducal countermark tells the holder not only what the money is, but who claims the authority to guarantee it.

That is why Heller's reverse matters. Heller does not need a completely independent monetary standard to make a political statement. Every Heller-issued coin quietly asserts that the Duchy possesses enough authority to place its own mark on Valdegracian money.

Why Treasure Chests Still Exist

If banks, bills, and credit exist, why move precious metal at all?

Because financial systems require infrastructure. A remote colony may have no major bank. A regiment needs wages. A naval squadron needs cash. A colonial governor may need hard reserves. A distant trading post may trust silver more than any promise written in the Old World.

Governments also move specie between treasuries. Merchant houses sometimes need physical settlement. Wars disrupt credit networks. Banks fail. Communication breaks down.

So payroll ships, treasury convoys, bullion cargoes, strongboxes, and guarded chests remain part of the world.

A ship carrying 5,000 gold is not simply carrying treasure. Someone sent it. Someone expects it. Someone will notice if it does not arrive.

When Money Becomes a Weapon

War does not stop at the mint.

Governments can refuse enemy bank notes, freeze deposits, seize foreign assets, prohibit particular financial instruments, require money changers to report large exchanges, invalidate countermarks, or prevent banks from honoring certain bills.

Counterfeiting can attack confidence directly.

A false coin steals the value of one coin. A flood of convincing false bank notes can damage trust in an entire bank.

That makes bankers, engravers, printers, treasury officials, and money changers relevant to espionage. Financial warfare can cripple a port without a cannon being fired.

Money Leaves Tracks

Coins contain information: nation, mint, date, metal, ruler, state emblem, and countermarks.

Paper contains even more: issuer, signatures, serial numbers, stamps, date of issue, place of redemption, and sometimes named parties.

That makes money useful evidence.

  • A murdered courier carries newly minted Albion gold.
  • A supposedly poor dockworker has twenty gold pieces from an Albion naval-pay issue.
  • A captured smuggler carries Heller-stamped Valdegracian notes issued only days earlier.
  • A merchant claims never to have visited Eisenmark, but every silver coin in his purse is fresh Eisenmark mint.
  • A stolen payroll is traced through registered note numbers.
  • A forged Heller stamp is almost perfect, except it reproduces a treasury seal retired six years earlier.
  • A dead man carries a coin struck after the date he supposedly disappeared.

Money remembers where it has been.

The Wrong Coin

The innkeeper turned the gold piece beneath his thumb.

Albion.

“Good weight.”

“Then we're agreed.”

He turned it over.

“Wrong crown.”

“It's still gold.”

“Then the exchange house will be delighted to see you.”

The traveler produced a Valdegracian bank note. The innkeeper saw the Heller treasury stamp.

The note disappeared beneath the counter. The Albion gold slid back.

“Welcome to Heller.”

The Wrong Coin

Using Money at the Table

Money should make Mar de Oro feel alive. It should not turn the campaign into an accounting exercise.

For ordinary purchases, use the listed price and count coins normally.

1 platinum = 10 gold = 100 silver = 1,000 copper.

Do not calculate daily international exchange rates unless finance is genuinely important to the campaign. Make currency origin matter when it creates a better scene.

Game Master guidelines for handling coin, notes, and platinum at the table
SituationGM guideline
Trusted coinFace value.
Awkward foreign coinUsually accepted or exchanged at roughly a 10% loss.
Very difficult coinUp to 20% loss, verification, or bargaining.
Suspicious coinWeigh it, test it, negotiate.
Trusted bank noteNear face value where the issuer is recognized.
Foreign or unfamiliar noteExchange house, bank verification, or refusal.
PlatinumFull official value, but finding someone able and willing to exchange it may be the problem.

Use these only when they matter. Nobody needs an exchange scene every time the party crosses a border. But sometimes the coins themselves are the scene.

A Coin Is a Tiny Political Document

Modern money can feel anonymous. Money in Mar de Oro should not.

A Heller dockworker recognizes the Heller reverse. An Albion officer knows military pay coin. A Valdegracian banker recognizes an old mint issue. A merchant knows which banker's signature is good. A smuggler knows which exchange house asks no questions. A sailor knows what three months of unpaid silver feels like. A privateer knows what a prize might be worth.

And a tavern keeper knows when someone has placed the wrong ruler's face on the counter.

That is why money matters. Not because players should calculate six exchange rates before ordering supper. Because every coin has travelled through the world before reaching their hand. Every bank note is somebody's promise. Every debt depends on somebody's name.

The value may be stamped on the coin. Whether you can spend it is determined by the world around you.
