Up until recently, copper coins contained very small quantities of tin, zinc or even aluminium, and were perhaps more accurately referred to as bronze coins. Currently, due to the increasing cost of copper, there is a trend away from minting copper coins, and many, what were previously copper coins, are now being made from copper plated steel.

Are copper coins pure copper?
Pure copper has not been used to make British coins for about 150 years. From 1860, British "copper" coins were made from bronze which consisted mostly of copper varying from 95 to 97% copper. From 1992, British "copper" coins were made from copper plated steel. Ironically, copper is used to make modern "silver" coins (cupro-nickel) consisting usually of 75% copper and 25% nickel.
What is mixed with copper to make brass?
