The CSA Half Dollars minted in 1861 refer to the Confederate States of America coins produced during the American Civil War. These 50-cent pieces were struck in limited numbers due to the Confederacy's short existence and the tumultuous economic conditions of the time. The coins were made primarily of silver and feature distinctive designs emblematic of the Confederacy, making them highly sought after by collectors. Their historical significance, combined with their rarity, contributes to their value in the numismatic market.
