Description

This proof striking of the 1852/1 Humbert twenty-dollar gold piece combines two layers of numismatic distinction: the proof finish and the overdate variety. Proof territorial gold coins are among the rarest objects in American numismatics, and a proof overdate from the U.S. Assay Office represents an almost inconceivable level of rarity. The proof finish reveals the full quality of the die work on Humbert’s double eagle, with mirror fields and frosted devices that showcase details lost on circulated business strikes. The 1852/1 overdate is clearly visible in the date, with traces of the underlying 1 discernible beneath the 2. The existence of this proof indicates that Humbert or senior officials at the assay office maintained the practice of producing special-quality pieces for record-keeping or presentation purposes.

Rarity Notes

Extremely rare, unique. A proof overdate territorial gold double eagle is among the most important American coins.
