These SILVER COINS are US Constitutional 90% Silver Coins, #ladiesofhive #silver generally refers to old US currency coins
whose value is based on the silver bullion value of the silver content they contain.
These are 90% silver coins minted by the US Government pre-1965 (half dollars, quarters, and dimes).
I remember over 20 years ago the odds in finding one of these is 1 coin in every $10,000 in change you handle!
