The Royal Mint has unveiled a 50p coin commemorating the BBC's centenary.Although the King's effigy has already been unveiled, the coins will feature an image of the late Queen as they were produced before her death in September and will not be re-struck in order to "minimise waste or unnecessary environmental impact".The coin's depiction of the Queen is expected to create a "high demand" among collectors, a Royal Mint official said.
