Collectible coins, particularly in the United States, include a variety of denominations and designs, each reflecting different historical contexts and artistic influences. The five-cent nickel and half-dime coins are notable examples. The Seated Liberty design, featured on half dimes between 1837 and 1873, represents American ideals of liberty and has become a popular choice among collectors. The 1851 Seated Liberty half dime, minted in Philadelphia, is particularly sought after due to its historical significance and the limited number of coins still in circulation or preserved in good condition.
