The Royal Mint is considered to have begun officially in 886 AD, and has since continued to mint coins for Great Britain. The site of the mint was moved in 1966 from London to Wales and faced difficult times in the early 1970s when a slump was going on in the western world. From the slump, the mint never fully recovered until 2012, when they were chosen to manufacture the 2012 Olympic Games medals. The Royal Mint also has a visitor facility accessible for Mint guests in a brand new visitor center, which has also helped with the financial status of the mint. The British Royal Mint revealed in 2015 that they will start manufacturing platinum and silver bullions.
The obverse features a very similar to all products produced by the British Royal Mint, Australian Perth Mint, Royal Canadian Mint, and New Zealand Mint since 1983. This familiar design features a recent depiction of Her Majesty Queen Elizabeth wearing her crown. Around her image are the words “100 POUNDS”, “ELIZABETH II”, “D.G.”, & “REG F.D.” The DG REG FD stands for “Dei Gratia Regina Fidei Defensor” which is Latin for “By the grace of God, Queen, Defender of the Faith”.
The reverse of this British platinum coin features the White Lion of Mortimer standing on its hind legs, with a shield in front of the lion. The shield in front of the lion features a white rose encircled by a golden sun, which represents two distinct badges that were both used by King Edward IV and King Richard III. The words “WHITE LION OF MORTIMER”, “1 OZ”, “FINE PLATINUM”, “999.5”, “2021” and the designer’s initials “JC” minted around the lion.
