1 Groschen - Günther XLI and John Günther Spitzgroschen

Günther XLI and his brother Johann Günther I ruled Schwarzburg jointly from 1552, a co-regency arrangement common among the smaller German territories that complicated mint administration considerably. Their groschen issues of this period fall squarely within the Spitzgroschen tradition — a denomination type whose tapered flan shape was already archaic by the mid-sixteenth century, a deliberate stylistic conservatism that distinguished territorial coinage from the broader Taler-driven monetary reforms sweeping the Empire.

Schwarzburg's silver came primarily from mines in the Thuringian highlands, and output was modest enough that surviving examples from this fifteen-year window tend to cluster in a narrow range of die combinations catalogued by Bethe.
