France
Napoleon gold Mint Error 20 Francs L'An 12 (1803/04)-A AU55 NGC, Paris mint, KM651. Mirror brockage on reverse. For the type, anything approaching Mint State appearance would easily be considered desirable. Almost never encountered in gold, the fact that the chirality of this brockage is so profound only further supplements the intriguing allure. Fundamentally pleasing surfaces, one of a kind character, and what is sure to be a conversation piece in its future owner's collection.
