25p Crown: Queen Mother's 80th Birthday
Years of issue:
A crown tariffed at 25 pence was issued in August 1980 to celebrate the 80th birthday of the Queen Mother. Her left facing portrait on the reverse of the coin was the first time a person other than the reigning monarch had been portrayed on a British coin in their own lifetime. The design features her effigy surrounded by a radiating pattern of bows and lions; a pun on her family name of Bowes-Lyon.
