THE UNA AND THE LION SEGMENTED COLLAR

Some great images I saw this week on a Royal Mint Museum Facebook post. -Editor

The Una and the Lion five-pound coin of 1839 is a celebrated work by William Wyon, admired for its artistry and precision. Its raised lettered edge was struck using a segmented collar, a complex technique requiring the collar to separate after striking.

The original three segments used in its production were rediscovered during the Royal Mint's move to South Wales and joined the Museum's collection in the late 1960s.
