Collectible coins, also known as numismatic coins, are valued for their historical significance, rarity, and condition rather than just their metal content. The Seated Liberty Half Dollar, minted from 1839 to 1891, features a design of Lady Liberty seated and symbolizes freedom. The 1871 Seated Liberty Half Dollar is particularly sought after by collectors, with an mintage of approximately 49,000 coins, contributing to its scarcity and appeal in numismatic circles. This coin represents a significant era in American coinage and is often included in collections focused on U.S. silver coins.
