16 Gute Groschen - Charles William Ferdinand

Charles William Ferdinand ruled Brunswick-Wolfenbüttel from 1773 until his mortal wounding at the Battle of Auerstedt in 1806 — the same engagement that effectively ended the principality's independence under the old Reich structure. The 16 Gute Groschen denomination was a north German accounting unit tied to the Reichsthaler system, with 24 Gute Groschen equaling one Reichsthaler, making this piece a two-thirds thaler equivalent used heavily in regional trade and wage payment.

The long emission window of 1784–1805 means multiple die marriages exist across the run, and examples from the final years of striking carry particular historical weight given how abruptly the issuing authority dissolved after Auerstedt.
