Ducat - Ksawery as Polish Prince Drezno mint

Friedrich Christian's son Ksawery (Xavier) governed Poland as regent following the death of Augustus III in 1763, during the interregnum before Stanisław August Poniatowski's election consolidated Russian influence over the Commonwealth. He never became king. These ducats were struck at Dresden — the Saxon electoral mint — rather than on Polish soil, a practical arrangement that reflected where actual Saxon dynastic power resided, whatever Ksawery's nominal Polish title suggested.

The three Kop references correspond to die variants across the 1766–1768 production run, differentiated by minor legend and date rendering.
