Currency
No matter what version of Dungeons & Dragons you play, you are familiar with coins of one sort or another. But exactly what coins are present in your game, what the conversion rate is between them, and even what they weigh, changes from version to version.
Holmes Edition
I started playing with the Holmes edition of d&d (sometimes referred to as “the blue book”). Each coin weighed one tenth of a pound and had the following conversion rates:
| 5 Copper Pieces | = | 1 Silver Piece | |
| 5 Silver Pieces | = | 1 Electrum Piece | |
| 2 Electrum Pieces | = | 1 Gold Piece | |
| 5 Gold Pieces | = | 1 Platinum Piece |
| 50 Copper = 10 Silver = 2 Electrum = 1 Gold = 1/5 Platinum |
First Edition
Advanced Dungeons & Dragons (1e) was very similar. The only difference was that copper and silver pieces were devalued. Each coin continued to weigh one tenth of a pound.
| 10 Copper Pieces | = | 1 Silver Piece | |
| 10 Silver Pieces | = | 1 Electrum Piece | |
| 2 Electrum Pieces | = | 1 Gold Piece | |
| 5 Gold Pieces | = | 1 Platinum Piece |
| 200 Copper = 20 Silver = 2 Electrum = 1 Gold = 1/5 Platinum |
Second Edition
Second edition revalued copper and silver up to about halfway between their Holmes and 1e values. Everything else remained the same. Many people started equating coins to pennies, dimes, fifty-cent pieces, dollars, and five dollar pieces. This comparison existed before but became more prevalent at this point.
| 10 Copper Pieces | = | 1 Silver Piece | |
| 5 Silver Pieces | = | 1 Electrum Piece | |
| 2 Electrum Pieces | = | 1 Gold Piece | |
| 5 Gold Pieces | = | 1 Platinum Piece |
| 100 Copper = 10 Silver = 2 Electrum = 1 Gold = 1/5 Platinum |
Final Edition
Third edition dropped the electrum piece and changed the weight of all the coins to 1/50 of a pound. This system persists through 3.5e and Path Finder. The electrum piece, like it’s fifty-cent piece equivalent, was always an odd coin and not particularly useful. Getting rid of it certainly didn’t hurt anything. Dropping the weight of the coins cut their size considerably, making them much more convenient to deal with.
| 10 Copper Pieces | = | 1 Silver Piece | |
| 10 Silver Pieces | = | 1 Gold Piece | |
| 5 Gold Pieces | = | 1 Platinum Piece |
| 100 Copper = 10 Silver = 1 Gold = 1/5 Platinum |
That Other Game With the Same Name
My favorite distinction between D&D and 4e is that in D&D characters are people striving to become heroes, while in 4e characters are heroes predestined to become gods. The currency changes went through a drastic change which emphasizes that fact. Platinum pieces are now worth 20 times what they were before. In addition, a new piece of currency was added. The Astral Diamond weighs a tenth of what the other coins weigh and is worth 10,000 gold pieces.
| 10 Copper Pieces | = | 1 Silver Piece | |
| 10 Silver Pieces | = | 1 Gold Piece | |
| 100 Gold Pieces | = | 1 Platinum Piece | |
| 100 Platinum Pieces | = | 1 Astral Diamond |
| 100 Copper = 10 Silver = 1 Gold = 1/100 Platinum = 1/10,000 Astral Diamond |
Greyhawk Currency
In the book “Saga of Old City”, Gary Gygax details the coinage used within his Greyhawk Campaign. He doesn’t state how much each coin weighs, but he covered the conversion rates quite explicitly. Since brass and bronze are very similar metals, and 10 brass bits are worth 1 bronze zee, I assume the bronze coin is therefore larger and heavier. This being the case, I wouldn’t be surprised if all the coins had different weights.
| 5 Iron Drabs | = | 1 Brass Bit | |
| 10 Brass Bits | = | 1 Bronze Zee | |
| 5 Bronze Zees | = | 1 Copper Common | |
| 4 Copper Commons | = | 1 Silver Noble | |
| 5 Silver Nobles | = | 1 Electrum Lucky | |
| 10 Electrum Luckies | = | 1 Gold Orb | |
| 1 Gold Orb + 1 Electrum Lucky | = | 1 Platinum Plate |
| 50,000 Iron = 10,000 Brass = 1,000 Bronze = 200 Copper = 50 Silver = 10 Electrum = 1 Gold |
Obviously, this system is a bit more complicated but it certainly adds a bit of flavor.
Throughout the Gord the Rogue books, and as evidenced by the three coins below copper, it is obvious that the value of these coins is much greater in his economy than in any of the above listed versions of d&d. In his books, a purse with ten gold orbs is quite a treasure, even to fairly high level characters.
Dragon Quest
In another game, SPI’s Dragon Quest (later bought and shelved by TSR), yet another system of coinage is used. The weight of each coin varies from 1-4 ounces (from 16 coins per pound to 4 coins per pound).
| 4 Copper Farthing (4oz) | = | 1 Silver Penny | |
| 12 Silver Pennies (1oz) | = | 1 Gold Shilling | |
| 1.5 Gold Shilling (1oz) | = | 1 Platinum Shilling | |
| 14 Platinum Shillings (1oz) | = | 1 Truesilver Guinea (2oz) |
| 1,008 Copper = 252 Silver = 21 Gold = 14 Platinum = 1 Truesilver |
So What
No real point here. I just thought it might be interesting to compare the different currencies used in different editions and other games.
Well, Maybe a Little Point
All this does beg the question “what if we used something other than coins?”. Actually, I do use other forms of currency in my game. Coins are used by humans and some of the other races that they trade with. But not all races prize coins.
Dwarves, with their love of precious metals, obviously embrace gold and silver coins. They also use other precious metals (among themselves) that they never trade with outsiders. Gnomes, on the other hand, have little interest in precious metals but are extremely interested in gems of all sort. Ogres, ettins, and others of limited intelligence, have trouble grasping anything as esoteric as there being any value tied up in coins. If they trade at all, it is in food, furs, and other items that they can actually use. Orcs, goblins, and other intelligent races, will use coins to trade with humans, food and furs to trade with ogres, but may use something else entirely to trade among themselves.
That being the case, what about ruins of lost civilizations? Those people may well have used something other than coins. If so, then any treasure cache found in such a ruins would contain those items instead of coins. It could be something as mundane as bones or shells. Or it could be something unusual. In the series Babylon 5, there were a race of soul hunters who collected souls within special containers. On Charmed, there were demons who collected and traded powers. A powerful ancient civilization may have scoffed at outsiders and trapped any they encountered within magical devices (such as the item Iron Flask). They could then have used these trapped beings as currency. There are all sorts of alternatives to coins that could lead to some interesting gaming possibilities.
















With the near-ancient invention of the coin (Pre-Greek Civilisation), it seems sensible that ancient civilisations used ancient coins… But what those coins are worth to each other or to whom is of course vastly different.
Just take the example of Spanish Dubloons. They weigh around 7g of gold and would be worth around $250-300 (AUD & USD) if purchased currently.
In my own systems I prefer to have moneychangers exchange weight for weight of coins of the same kind. Moneychangers would also have ‘factored’ scales to exchange between denominations (i.e. an ancient gold coin does not weigh the same as a modern gold coin, so I’ll adjust the weigh-beam to allow me to convert the gold coin into silver or copper/bronze coins). Of course, it’s always worth keeping moneychangers around as they provide the chance for more adventures but also can allow you to ‘over-reward’ your players knowing that the moneychangers will take a cut.
Good point. I didn’t think to include anything about moneychangers. I’ve always used them (even in campaigns that didn’t offer banks). Foreign coins (from other kingdoms) and ancient coins are not accepted anywhere so characters must exchange them for proper coins of the realm. Also, characters with piles of copper pieces could change them into more portable currency. Both of these services were provided for a 10% fee.
Moneychangers are doubly useful in that they also compensate for the shaving of coins, by weighing coins to ensure full weight. This was actually a common RL occurance, where people would shave a bit off of each coin in order to profit from the gold or silver shavings. Ridges along the edge of the coin, as in the US quarter, are another deterrent.
My own idea…
MONEYCHANGERS
Heroes and Merchants face a frequent dilemma: their coins are not valid in every city in the world. Ancient coins found in ruins, out of date coins, coins from far civilisations all need to be exchanged into the currency valid in the realm. This section doesn’t provide a hard-and-fast rule on the fees charged by a moneychanger, what value of valid coins you will get or the process they will use to determine the value of your ancient coins.
Exchanging Coins
Most Moneychangers will exchange coins based on weight. Of course they will take a fee for exchanging coins; usually this will be for between 1 coin in 20 and 1 coin in 10. Many also charge a minimum fee for exchanging coins.
They will also exchange between denominations using ‘factored scales’. If 10 silver coins equalled 1 gold coin, the scales would balance when 10 valid silver coins is placed against 1 valid gold coin.
Taxation
Moneychangers can often double as tax collectors, since they have a large number of coins at their disposal and are always present in marketplaces. Some cities charge taxes for exchanging large volumes of coins. These vary by the city, circumstances and the ruler (read: Your GM will let you know).
Thanks for the concise conversions. I’m writing a fantasy novel set in King Arthur’s time so I needed a simple conversion rate between copper, silver and gold. Kinda remembered the old D&D rules and needed to check if I had it right without pawing through my attic for the old books.
Got everything I needed right here. I went with final edition conversions.
