Details

The Kagin-7 Humbert slug is the second use of the 1851 $50 Reeded Edge 887-Thousandths obverse die and is always found with moderate to heavy die rust. Its reverse uses a new die with a smaller target at its center and a “racetrack” with a smaller diameter than the planchet, so that the outer engine turning is generally at least 70% visible.

Obverse: Eagle clutching shield and scroll AUGUSTUS HUMBERT UNITED STATES ASSAYER OF GOLD CALIFORNIA 1851 UNITED STATES OF AMERICA. FIFTY DOLLS. 887 THOUs.

Reverse: Engine turning with small target.
