Production of the Churchill Crown began on 11 October 1965, and stopped in the summer of 1966. The crown was worth five shillings (a shilling being 12 pre-decimal pence) until decimalisation in February 1971, and was also the basis of other denominations such as the half crown and double crown. The last five shilling piece was minted in 1965. The crown coin was nicknamed the "dollar", but is not to be confused
