Royal mint. All three are part of the 1953 Coronation set of Queen Elizabeth II. Each has the granular, matte-like surfaces showing that they were struck using sand-blasted dies. These Matte pieces were struck in very limited numbers (reportedly only 3-4 pieces), to be used for photographic purposes at the Royal Mint. Each is richly toned in shades of chocolate-brown. Exceedingly rare.
