In 2013 to celebrate the 30th Anniversary of the first £1 One Pound Silver Coin, the Royal Mint released a very special Limited Issue Royal Arms £1 One Pound Silver Proof Coin struck in solid .925 Sterling Silver.
The reverse is the Royal Arms design by Eric Sewell and the obverse is a portrait of Queen Elizabeth II, designed by Ian Rank Broadley.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
