Historically, many coinage metals (or alloys) are from the three nonradioactive members of group 11 of the periodic table: copper, silver and gold. However, there are many more, even for coins made from intrinsically precious metals.Precious metals are always used in bullion coins and some collectable coins.he term is not perfectly defined, however, since a number of metals have been used to make demonstration coins which have never been used to make monetized coins for any nation-state, but could be.
This is where the outer parts of the coin are made from a different color metal to the inner part of the coin. This is used as a technique to reduce the counterfeiting of higher value coins as seen in the â¬1 and â¬2 coins and with the British Â£2 coin. **Clad coins differ from plated coins in the following way. Clad coins have a sheet, on either side, of the outer metal that does not cover the edge of the coin. In this case, the inner metal can be seen on the edge. An example is the US quarter.
