In 1992 the Royal Mint decided to reduce the size of the 10 Pence Piece. It had stayed the same size as the old Florin since decimal coins were first issued in 1968.
To honour this event and the change over from large to small size, they struck Proof examples of the old Large Sized 10p and Proof examples of the new Small Sized 10p, both in Proof Sterling Silver. The large sized coins were only available in base metal in the Mint and Proof Sets of that year, none were struck for circulation. The Sterling Silver pieces are only available in this set and were struck for collectors.
The ‘new’ small sized 10p is now over 20 years old and we think this pair is a very interesting combination. After all, where else can you get both sizes in Proof Sterling Silver?
