Stamped and Raw Coin

Stamped coin, or stamps, are the main currency of the Fedheran Unity. They are coins stamped with the Mytheran insignia and its assigned worth. These come in bronze, copper, silver, and gold with their worth calculated by their weight (and confirmed by the stamp). Other materials can receive the same stamp given its quality and worth has been confirmed by the Judges College or the Council of Commerce.
Raw coin are an unstamped currency. This is usually unstamped, or stamped but broken, bronze, copper or silver coins (rarely gold) and sometimes uncut gems. A certified merchant would weigh a raw coin before accepting as payment, then exchange them at a branch of the Council of Commerce for stamped coin.
