Description

A proof-quality copper die trial of the 1861 Clark, Gruber & Company $10 eagle, distinguished from the regular die trial by its carefully prepared surfaces and deliberate striking characteristics. Proof impressions from frontier mints are exceptionally unusual, as private coiners generally lacked the time, equipment, and motivation to produce presentation-quality strikes. The existence of a proof die trial indicates that Clark Gruber took their die-testing process seriously, or that this piece was produced as a special presentation item. The 1861 eagle design, featuring the new Liberty Head obverse that replaced the earlier Pikes Peak motif, is shown here with the sharp detail and reflective fields characteristic of proof manufacture. Copper was the preferred metal for die trials because it was inexpensive, readily available, and soft enough to take a full impression without excessive stress on the dies. This proof die trial represents an intersection of two rare categories: Clark Gruber proof coinage and copper die trials, making it one of the most significant pieces in the Clark Gruber series.

Rarity Notes

Of the highest rarity. Proof copper die trials from any territorial mint are essentially unique. This piece exists in single digits or fewer.
