6 Ducats - Henry Wenceslaus and Charles Frederick I

Münsterberg-Oels was a fragmented Silesian duchy jointly administered by Piast-lineage princes whose political position became precarious almost immediately after this coin was struck. The year 1620 — the same year as White Mountain — is not coincidental. Multi-ducat gold pieces of this size were produced less for circulation than for diplomatic gifting and emergency wealth storage, and the Battle of White Mountain in November of that year would effectively end the independent political ambitions of Protestant Silesian lords like these two.

Henry Wenceslaus died in 1639; Charles Frederick I predeceased him in 1625, making joint issues of this duchy exceptionally short-lived by any measure.
