The Fifty Cents coin, commonly referred to as the half dollar, was first introduced in the United States in 1794. The 1864 Fifty Cents coin is particularly notable due to its design, which features a representation of Liberty on the obverse and an eagle on the reverse. This era of coinage is part of the broader series of silver coins, with half dollars typically minted in 90% silver. Collectible examples from this year can vary in value based on their condition, mintage, and demand among collectors.
