⅓ Thaler - Max Gandolf von Kuenburg Brandenburg-Prussia, Countermarked

Max Gandolf von Kuenburg, Archbishop of Salzburg from 1668 to 1687, ruled during a period of aggressive Counter-Reformation policy in the region — his expulsion of Protestant miners from the Defereggen Valley in 1684 being among the more documented episodes of confessional hardship in the late Habsburg lands. The Brandenburg-Prussia countermark on this piece reflects the complex monetary traffic of the Holy Roman Empire, where foreign silver regularly entered circulation and local authorities stamped it to validate or regulate its use within their jurisdiction.

The Zöttl reference range 2088.79–2088.83 accounts for minor countermark placement variants, not die differences in the host coin itself.
