Each geographical area often has its own local currency, but there is a world standard of coinage that is generally preferred instead of local coinage. Generally the value of coins is measured by the weight of precious metals each contains. The most common coins are:
Platinum Wheels: A high-value currency used for exceedingly rare and substantial transactions. Its usage is limited to particularly wealthy individuals and significant economic exchanges.
Gold Crowns: A relatively rare currency, mainly reserved for larger transactions or significant purchases. It's not commonly used in everyday transactions without expecting change.
Silver Crescents: The primary currency used in most regions and nations, valued for its silver content and widely accepted for various transactions.
Copper Moons: The smallest denomination, made of copper, used for small transactions or given as change for more significant exchanges.
The coins are based on a ten to one system whereby ten copper moons are equivalent to one silver crescent. Ten silver crescents are equal to on gold crown. The exception is it takes one hundred gold crowns to reach the value of a single platinum wheel. The usage of gold as a day to day currency is rare and reserved for larger transactions.
