These substantial silver pieces are collectible bullion coins issued by the United States Mint. Each coin features a different national park or site from each of the 50 states, the District of Columbia, and the five U.S. territories. Struck in five troy ounces of .999 fine silver, they are larger and heavier than traditional bullion coins, presenting a significant silver investment option. Their obverse design consistently features a modified version of the 1932 portrait of George Washington by John Flanagan.
The intrinsic value of these silver items stems from their precious metal content, making them a hedge against inflation and currency devaluation. Beyond their bullion value, their limited mintage and collectibility contribute to potential appreciation in the secondary market. They provide a tangible asset that diversifies investment portfolios and offers a connection to American history and natural landmarks. The series itself served to generate revenue for the US Mint and promote awareness of the represented national sites.
