1 Ducat - Johann Ehrenreich Tin Trial Strike

The Counts of Sprinzenstein were a minor Austrian noble house whose coining privileges were among the last exercised by smaller imperial vassals before Habsburg centralization steadily absorbed such rights through the eighteenth century. Trial strikes in tin were a standard step in the die approval process — submitted to confirm design and dimensions before gold flans were committed. That this one survives is fortunate; tin trials were working tools, not keepsakes, and most were melted or simply lost.
