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 Description
