5 Mark - William II Reverse Trial

Trial pieces from the Stuttgart mint documenting reverse die testing are rarely cataloged with any precision, but Schaaf's attribution system for Wilhelmine-era probes is unusually thorough. This copper strike — well over twice the weight of the production silver — served as a mechanical test for die alignment and press pressure, not as a presentation piece. The Staatliche Münze Baden-Württemberg issued trials in base metal specifically to avoid wasting silver blanks on setup runs.

Schaaf 176/G3 places this within a documented sequence of reverse-only trials for the 1910 Stuttgart coinage program.
