Collectible coins, particularly in the United States, include iconic types like the Morgan and Peace Dollars, which were originally minted in the late 19th and early 20th centuries. Reproductions of these coins, such as those minted in 2021 in Philadelphia, serve to commemorate their historical significance while providing an accessible option for collectors. The original Morgan Dollar was produced from 1878 to 1904 and then again in 1921, while the Peace Dollar was minted from 1921 to 1935, symbolizing peace following World War I.
