In 2011 the Royal Mint released a very Limited Issue Britannia 50p Fifty Pence Silver Proof Coin struck in solid .958 and weighing one quarter of an ounce of fine Silver.
In a new and innovative interpretation, he has united two powerful symbols of Britain today, placing Britannia at the heart of a billowing Union Flag. And, to the delight of the collectors past and present, he has chosen to picture her seated with trident and shield in the manner of the classic image that has featured on the pre-decimal pennies of every monarch since Charles II, while the obverse features the portrait of Her Majesty The Queen by Ian Rank-Broadley FRBS.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
