Copper, nickel, silver and gold are the base metals used in coins. Well, gold maybe not so much. Sorry, couldn't find the physical properties. Maybe someone else will add the info.
Chemical properties of Gold:
- nonreactive to most acids
- not readily forming compounds with oxygen
- highly malleable
- excellent electrical conductivity
Chemical properties of Silver:
- nonreactive to most acids
- not readily forming compounds with oxygen
- very malleable
- the best of all metals in electrical conductivity
Chemical properties of Copper:
- nonreactive to most acids
- not readily forming compounds with oxygen
- very malleable
- the second best of all metals in electrical conductivity
