when did the half crown go out of circulation
Half crown (British coin) The half crown was a denomination of British money, equivalent to two shillings and sixpence, or one-eighth of a pound. The half crown was first issued in 1549, in the reign of Edward VI. No half crowns were issued in the reign of Mary, but from the reign of Elizabeth I half crowns were issued in every reign except Edward VIII, until the coins were discontinued in 1967.
Crown (British coin) Always a heavy silver coin weighing around one ounce, during the 19th and 20th centuries the crown declined from being a real means of exchange to being a coin rarely spent and minted for commemorative purposes only. In that format it has continued to be minted, even following decimalisation of the British currency in 1971. However, as the result of inflation the value of the coin was revised upwards in 1990 to five pounds.[1]
