1 Ducat - Henry III and Charles II Reichenstein

Münsterberg-Oels was a Silesian Piast duchy that passed through complex inheritance arrangements throughout the sixteenth century. Henry III and Charles II ruled jointly as co-dukes — a dynastic arrangement common among the fragmented Silesian lines, where territorial subdivision had produced a patchwork of small co-rulerships rather than consolidated principalities. Joint-issue ducats from such pairings have inherently low mintage ceilings; a small duchy producing a single denomination across a seven-year window under two names rarely struck in volume.

The Freiberg reference Fr#3235 places this squarely among the rarest categories of Silesian Renaissance gold.
