Buy Proof £100 / One Hundred Pound Proof United Kingdom Platinum Jubilee Coins
We stock a wide selection of proof coins, primarily Royal Mint proof sets. If a particular item you're looking for isn't listed here, it's worth enquiring with us on availability as we currently only have a fraction of our phsical stock listed.
Proof coins are struck to a far higher quality, compared to their bullion equivalents. For a more detailed explanation, please see our article explaining the difference between proof vs bullion coins.
2022 was the year of Her Majesty the Queen's Platinum Jubilee. She's the first British monarch to celebrate seventy years on the throne and The Royal Mint marked the occasion with an extensive range of commemorative coinage. There's a new equestrian portrait and we've got new £5 Crowns, the first royal Fifty Pence and more in gold, silver and - appropriately - platinum.
