Coin Hunter sells the Paddington at the Palace 50p as a black card encapsulated Circulation or Brilliant Uncirculated (BU) Coin. Paddington Colour Silver Proof and Gold Proof are available direct from The Royal Mint.
If you're looking for this Paddington design for your 50p coin collection, keep checking you change as it's in circulation now. You can buy a special Paddington 50p album which holds the 2 coins in this set.
If you shop online or often use contactless cards instead of cash in shops, why not try checking virtual change online using the Coin Hunter app. It's fun, easy to play and you can build your real coin collection - any coin you see can be ordered via the app and delivered to your home.
A well know checker of change is, at present, the only supplier of brilliant uncirculated coins that are not in the official Royal Mint folders. The blue card coins are priced at £3.99 for newly released 50p coins. The Paddington at Buckingham Palace design will soon be available from Coin Hunter.
