Precious metals: Stuff which is of no or very little use by itself, but doesn't degrade much in typical conditions and is rather hard to find or labour-intensive to acquire.

List: Gold, Silver, Platinum, Palladium, Aluminium (pre-Hall-Héroult process), Copper, rare fantasy metals

Coins: Made of precious metals or their alloys, they have a *value* equal to its metal's value and a *form*, including *marks* which determine who *minted* them. Usually, a coin is accepted only in the origin territory for its full value, everywhere else you have to accept (up to 50%) less value.
