Watch List notes:

FRANCE: Third Republic, 1871-1940, white metal 1 franc, 1870-E, cf. Mazard-2127, essai pattern ("E" for "essai") in white metal for the silver franc (KM-822), presumably struck at the Paris mint, encapsulated by NGC in the 1980s, NGC graded Proof 65, RRRR. We have been unable to find any specific information for this pattern type, and it is possibly unpublished in white metal (Mazard lists #2127 only in silver, marked with his second highest rarity level, R5).

Estimate: 1,000-1,200 USD
