All the talk lately about decimal coins
I bought two a few years ago as both were different and came with a Royal Mint letter.
A 1999 Twenty pence struck on a one pence blank.
Royal mint say...A copper -plated steel blank intended for a 1p piece has become mixed in with 20p blanks and has been struck by 20p dies in the normal way.
A 2002 SILVER two pence.
Royal mint say.....As with the 10p piece of 2001, this coin was struck on a blank intended for an overseas coin.
Would think with the letter aswell quite unusual.
£95 for both including Special delivery.
Pete.
