6 Kreuzers - Frederick Günther

Schwarzburg-Rudolstadt was one of the smallest sovereign states in the German Confederation, covering barely 940 square kilometers with a population under 70,000. Frederick Günther ruled for over six decades — the longest reign in the principality's history — yet the fiscal reality of such a minor state meant billon coinage like this kreuzer served a genuinely practical function in daily market transactions rather than any political assertion of independence.

The .333 fineness places this firmly in the degraded silver tradition that persisted across the smaller German states well into the mid-19th century, resisted only by those with the mint capacity and silver reserves to do better.
