This specimen was lot 30663 in Heritage sale 3081 (New York, January 2020), where it sold for $8,400. The catalog description[1] noted, "German States: Prussia. Wilhelm I gold Proof 20 Mark 1873-A PR65 Deep Cameo PCGS, Berlin mint. Mintage unlisted in the Standard Catalog of World Coins. A gem selection representing the first of its date that we have sold in Proof format, a testament to the type's relative scarcity. Admirably mirrored fields are complemented by frosted devices, yielding a complete and appreciable cameo effect. From the Caranett Collection." This type was struck 1871-73 in substantial numbers from the Berlin (mintmark "A"), Breslau (mintmark "B") and Cleve (mintmark "C") mints during the reign of William I, emperor of Germany 1871-88. It was superseded in 1874 by a revised reverse. Tho this later type was struck 1874-88, it is not as common as the type shown here. There is a concurrent ten mark gold piece (Fr-3819) with a similar design.

Recorded mintage: 9,062,648 including proofs.

Specification: 7.96 g, .900 fine gold, .230 troy oz AGW.

Catalog reference: Fr-3813, KM 501, J-243.
