Collectible coins, also known as numismatics, encompass a variety of currency types sought after for their historical, artistic, or intrinsic value. The United States Mint produced the One Dollar Peace Dollar series from 1921 to 1935, commemorating the end of World War I and symbolizing peace. The 1922 Peace Dollar is particularly notable among collectors, with varying prices depending on its condition and rarity, including its mint mark. Enthusiasts often seek to acquire these coins for their significance and potential investment value.
