The Half Crown was a British coin that was worth two shillings and sixpence, or one-eighth of a pound. It was introduced in 1549 during the reign of King Edward VI and continued to be used until decimalization in 1971. The coin featured various designs over the years, often depicting the reigning monarch. The Half Crown was made of silver until 1947, when it was changed to a cupronickel composition. It was commonly used in everyday transactions and was popular among the public. After decimalization, the Half Crown was withdrawn from circulation and is now considered a collectible item.
