1 Groschen - Wenceslaus III Adam Teschen

Wenceslaus III Adam ruled Teschen from 1528 to 1579, navigating the duchy through the religious upheaval of the Reformation while maintaining a delicate balance between Habsburg overlordship and local autonomy. His coinage from this period is notably scarce — the Koppmann R3 rarity rating reflects genuine low survival rather than collector indifference. Teschen's mint output was modest by Silesian standards, and the three-year window of this groschen issue suggests either a brief authorization or a disruption in minting continuity that the documentary record has not fully resolved.
