15 Kreuzer

The Franconian Circle — one of the ten Imperial Circles of the Holy Roman Empire — issued coinage not as a sovereign state but as a collective administrative body, making its struck pieces constitutionally unusual. The 15 Kreuzer denomination was a workhorse of south German commerce, filling the gap between small copper and the heavier Taler-fraction coins that dominated long-distance trade.

KM#25 for this issuer is sparsely documented in the major references, and surviving examples are infrequently offered outside regional German sales.
