As of 2014, a 1945 George VI British silver sixpence coin carries a value of at least $1 in fine or better condition. Uncirculated copies of the half-shilling are valued at about $10.50 to collectors.
According to SilverAgeCoins, nearly 40 million 1945 coins were produced at The Royal Mint. The sixpence was composed of 50 percent silver through 1946, while coins produced during and after 1947 were made of a copper-nickel alloy. The British sixpence originated in 1551 and was minted until 1971 when it was rendered obsolete with the onset of decimalization. However, it remained legal tender until 1980, due to public outcry.
