This is a unique pair of Lincoln Medal obverse and reverse die trials. They are the Broken Column design and referenced as King-247. They are also referenced as Cunningham-9-460.

This pair of Lincoln medals are uniface since each die was tested separately on a lead planchet. Although the King reference book and NGC note that the diameter is 52mm, that is for the regular struck medal. These two die trials were struck out of the collar so the diameter is slightly larger. In addition the reverse die trial was double struck.

It is exciting that this unique pair of Lincoln Medal die trials survived and were authenticated and certified by NGC. This unique pair combines history, rarity and would be perfect for a collector of Lincoln medals and memorabilia or a collector of mint errors and die trials.
