1861 Proof Clark, Gruber & Co. Twenty Dollar - Copper, K-11, Gilt

Coin Details

Description

The 1861 Proof Clark, Gruber & Company Twenty Dollar in copper gilt, designated K-11, is a proof-quality off-metal striking with applied gold finish. This piece combines three premium features: proof strike, off-metal composition, and gilt surface treatment, placing it among the most desirable Clark Gruber off-metal patterns. The proof finish produces deeply mirrored fields and sharply defined design elements on the copper base, while the gilt layer adds the golden color of the intended gold composition. The careful preparation required for proof striking, combined with the additional gilding step, indicates these were produced with considerable deliberation and care. Proof gilt copper double eagle patterns from territorial mints represent the highest expression of the die sinker's art applied to frontier coinage. These pieces were almost certainly created for specific collectors or as presentation pieces for business partners.

Rarity Notes

Of the highest rarity. Proof copper gilt double eagle patterns may be unique or nearly so.
