This collection contains 90% silver coins minted by the US Treasury from 1932-1964, including dimes, quarters, and half dollars that once circulated in American commerce. These coins were removed from circulation during the 1965 Coinage Act when the US transitioned to copper-nickel clad coins due to rising silver prices. The bags represent the last era of circulating silver coinage in American history, making them both historical artifacts and precious metal investments. Each bag contains approximately $1000 face value of coins with roughly 715 troy ounces of silver content, providing substantial precious metal exposure.
