These coins are British legal tender, however, they cannot be used in shops or banks. These coins were initially sold by The Royal Mint as £20 coins which would be worth £20. Many people bought them from The Royal Mint believing that thy would be a good investment for the future.  Whilst we pride ourselves in being cheaper than the mint in most cases, we are unable to source these coins at a discount. We have managed to get a small supply in stock for informational purposes and to photograph. We are offering them for sale but with a premium. This is because we're a business and we don't work for free. We also only have a small supply and therefore will likely not have them in stock long.
