1851 Proof California Gold $50 - "887" $50 RE Augustus Humbert

Coin Details

Description

This proof striking of the 1851 Humbert fifty-dollar slug in 887 fineness with reeded edge represents the pinnacle of the assay office’s production quality. Proof territorial gold coins are extraordinarily rare, as the primary purpose was commercial circulation. Proof Humbert slugs exhibit sharper design details, more defined engine-turning, and mirror-like fields that contrast dramatically with heavily circulated business strikes constituting the vast majority of survivors. As a proof territorial gold issue, this coin occupies a unique position in American numismatics. There are no comparable proof issues from any other private or territorial Gold Rush minter.

Rarity Notes

Extremely rare, unique. Proof Humbert slugs are among the greatest rarities in American numismatics.
