1 Thaler - Hieronymus von Colloredo type 1b

Hieronymus von Colloredo became Prince-Archbishop of Salzburg in 1772 after a contentious conclave that required multiple ballots — he was not the favored candidate of the Salzburg chapter. His reign would become notorious partly for his treatment of the Mozarts: Wolfgang's difficult employment under Colloredo, and eventual humiliating dismissal in 1781, is among the better-documented employer-employee ruptures in 18th-century European court history. This thaler was struck the very year Colloredo assumed the see.

The "type 1b" distinction within Zöttl's classification reflects die variation among early Colloredo thalers — the series runs across multiple numbered references precisely because the Salzburg mint produced successive die marriages with documentable differences in the archbishop's bust rendering.
