Crown

A former coin in the United Kingdom equal in value to five shillings, or 1/4 of one British pound. The last crown was minted in 1965. Following decimalization in 1971, a 25-pence coin was minted to replace the crown. Informally, crowns were called dollars, recalling the time when one pound was worth four U.S. dollars.
