We are pleased to offer these 90% Silver Coins (John F. Kenndey Half Dollars, Walking Liberty Half Dollars, Morgan Peace Dollar .$50) that are in stock and ready to be shipped. Each bag has a combination of 90% silver coins dated 1964 and earlier. As customers know, the U.S. Mint began to decrease the amount of silver they used to produce circulated coins from 90% to 40 % beginning in 1965. Today the mint does not produce circulated coins with silver so these 90% silver coins are especially sought after.
