1 Pfennig 'Pfennig auf Würzburger Schlag' - John I

Wertheim's counts gained minting rights through imperial grant, and John I exploited them to produce small silver pfennigs aligned with the Würzburg monetary standard — a deliberate commercial decision, not administrative accident. Würzburger Schlag coinage circulated across Franconia's trade networks, and a provincial lord striking to that standard was effectively buying access to those routes.

Steinbach 185 is among the scarcer attributions from this county's output.
