Sovereign (British coin)
With the start of the First World War in 1914, the sovereign vanished from circulation in Britain, replaced by paper money, and it did not return after the war, though issues at colonial mints continued until 1932. The coin was still used in the Middle East, and demand rose in the 1950s, which the Royal Mint eventually responded to by striking new sovereigns in 1957. It has been struck since then both as a bullion coin and, beginning in 1979, for collectors. Though the sovereign is no longer in circulation, it is still legal tender in the United Kingdom.
