France 1828-A 20 francs
This issue, from the Paris mint, is one of a type struck during the reign of Charles X from four mints. This specimen was lot 1481 in Jean Elsen sale 94 (Brussels, December 2007), where it sold for 180 euro. Paris mint issues are reasonably common but the branch mint issues are all rare. A complete set of this type (1825-30) comprises 17 date and mintmark combinations. Le Franc  estimates a total mintage of 1.69 million for the whole type, compared to the preceding Louis XVIII 20 francs (1816-24), which number about 12.7 million.
All gold 20 francs were officially recalled in 1928 but effectively ceased to circulate in France during World War I.
