Sincona sale 51, lot 2465
This specimen was lot 2465 in Sincona sale 51 (Zurich, October 2018), where it did not sell. The catalog description[2] noted,
"II. Kaiserreich. Napoleon III. 1852-1870. 20 Francs 1858 BB, Strasbourg. Gadoury 1061. NGC AU58. (Second empire of France, Napoleon III, 1852-70, twenty francs of 1858, Strasbourg mint.)"
This type is one of the most common gold coins in existence (146 million minted 1853-60) yet is very difficult to assemble in choice condition. This is a better date, priced about double the common date (1858-A).

Recorded mintage: 2,067,740[1].

Specification: 6.45 g, .900 fine gold, 21 mm diameter, edge lettered DIEU PROTEGE LA FRANCE, designed by Jacques-Jean Barré.

Catalog reference: KM 781.2; Gadoury 1061, Fr-574, F.531/14.
