Many thanks Spence for your input. The 1815 Perpignan gold 20 francs has a "Q" mint mark. Louis XVIII started 1815 on the French throne but Napoleon escaped from Elba and took control of France for 100 days but after his deserved defeat at Waterloo King Louis returned to his throne for the remainder of 1815. Now I wonder if the 2 varieties reflect the 2 separate periods of 1815 that Louis was reigning.
