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.
Half dollar (United States coin) Though not commonly used today, half dollar coins have a long history of heavy use alongside other denominations of coinage, but have faded out of general circulation for many reasons. They were produced in fairly large quantities until the year 2002, when the U.S. Mint ceased production of the coin for general circulation. As a result of its decreasing usage, a large amount of pre-2002 half dollars remain in Federal Reserve vaults, prompting the change in production. Presently, collector half dollars can be ordered straight from the U.S. Mint,[2] and pre-2002 circulation half dollars may be ordered through most U.S. banks.
