The game's currency is measured in "☼", called "dwarfbucks" or "db's" by some players. Each item has a specific trade value in ☼, determined by what kind of object it is, what it is made of, and (sometimes) how well it was made. Dwarfbucks are an important measure in trade for bartering goods, allowing both the merchant and trader to judge whether the bartered trade goods are equivalent or not.
Metal crafters may strike physical coins out of any metal at the metalsmith's forge. This process requires one metal bar and one unit of fuel, and produces one stack of 500 coins. Each stack of coins has an effective item value of 10, meaning that the value of a stack is 10 x material value of the component metal, and a given coin is (10 x material value / 500) of the value of the metal bar that produced it. For example a silver bar is worth 10☼, so a stack of 500 silver coins will be worth 10 x 10 = 100☼, and each silver coin in the stack will be worth 10 x 10 / 500, or 0.2☼ (fractional ☼ values are never displayed). Because minted coins are always of base quality, they are not preferable as a trade good.
Coins have their own stockpile, and are stored in stacks of up to 500 coins. Each bin in a coin stockpile can hold up to six stacks, or 3,000 coins. Coins are named based on the year they are minted and the name of your fortress, and each coin in a given stack will be identical. For example if the year is 1058 and the name of the fortress is Thidalsokt, each coin in the stack will be a "Thidalsokt 1058" coin. The coins also depict images and figures from the history of the fortress. If the fortress is also the Mountainhome, the coins will be named after the civilization instead, and may depict the symbol and history of that civilization.
 Coins and the Dwarven Economy
Coins are intended for use with the dwarven economy, but the economy is not currently implemented in v0.31. In previous editions copper, silver, and gold coins had monetary value in addition to their intrinsic value, and dwarves would keep personal stacks of coins as part of their personal accounts. Coins of other metals were widely known as "collector's coins."
