1 Thaler - Charles I

Charles I ruled Brunswick-Wolfenbüttel from 1735 until his death in 1780, but the thaler series bearing his name spans only to 1770 — the final decade of his reign seeing a marked reduction in silver coinage output as the Seven Years' War drained the principality's treasury and disrupted mint operations at Zellerfeld. Brunswick-Wolfenbüttel had supplied troops to both sides of various eighteenth-century conflicts through subsidiary treaties, and the financial strain of maintaining those commitments showed directly in coinage volume.

Davenport's German Talers II cross-reference at 2146 distinguishes several die varieties across the run.
