   But I was thinking of using coins for blanks. Here in the UK post 1946   
   75/25 cupronickel florins are about 20p each in 1,000 lots - pre 1920   
   92% (sterling) silver ones can be had for about £11, 1920 to 50% silver   
   ones are about £5.   
      
   Florins are old pre-decimal currency, once worth 2/- (2 shillings) or   
   10p. 28mm diameter, weigh 11.3 grams. There are also the slightly larger   
   half-crowns.   
      
   You would have to anneal the cupronickel ones.   
      
   I don't know whether the US has anything similar. Or Canada, or Mexico...

   US currency has been decimal from the beginning. Canada changed from British   
   to US denominations in the middle 1800's.

   Pennies changed from 95% copper to plated zinc in 1982.
