This is a 1951 British Festival of Britain commemorative silver crown coin. Background and Theme: Issued in 1951 to commemorate Festival of Britain (a cultural renaissance event in Britain after World War II) and also to mark the 400th anniversary of the first British silver crown coin (issued in 1551). Obverse: Profile portrait of George VI, inscribed "GEORGIVS VI D:G: BR: OMN: REX F:D:" (meaning "George VI, King of Great Britain and all its territories, Defender of the Faith"), and the denomination "FIVE SHILLINGS" (5 shillings, or 1 crown). Reverse: The classic "St. George Slaying the Dragon" design (a traditional British coin design), with the year "1951" inscribed at the bottom. It is also often referred to as one of the "last horse and sword crown coins" (because the design of subsequent British crown coins was gradually adjusted). Packaging: Comes with the original box and certificate. The card indicates that the coin edge is engraved with the Latin inscription "MDCCCLI CIVIUM INDUSTRIA FLORET CIVITAS MCML" (corresponding to the English "1851 By the industry of its people the State flourishes 1951").
