In 1991 the Royal Mint released a very Limited Issue Britannia £100 One Hundred Pound Gold Proof Coin struck in solid 22 Carat Gold weighing one ounce of pure Gold.
Britannia first appeared as a provincial figure on a Roman Imperial Coin of the Emperor Hadrian (117 - 138 AD), although she did not feature on English Coins until the copper halfpennies and farthings of Charles II in 1672.
Since that time Britannia has continuously appeared on Britain's coinage.
The latest in a long line of elegant and beautifully designed Britannia can be found on the reverse of this One Ounce £100 One Hundred Pound Gold Proof Coin.
The design, by Philip Nathan, depicts Britannia as a standing figure for only the second time on United Kingdom coinage, the first being the much acclaimed Britannia by George William De Saulles used on the florins of Edward VII between 1902 and 1910.
The obverse of the 1991 Britannia £100 One Hundred Pound coin features Raphael Maklouf's portrait of Her Majesty Queen Elizabeth II.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
