   Nickel alloys are among the main metals used in today's coins but they are harder than other legacy coinage metals such as silver and gold alloys and therefore they cause even quicker die wear. Copper and copper alloys have been used in coinage for centuries because of their malleability and the ease with which they can be coined: however ...

   ^f Coinage metals: authors differ on whether roentgenium (Rg) is considered a coinage metal. It is in group 11, like the other coinage metals, and is expected to be chemically similar to gold. [ 17 ] On the other hand, being extremely radioactive and short-lived, it cannot actually be used for coinage as the name suggests, and on that basis it ...
