Dwugrosz koronny - Stanisław August Poniatowski Warszawa mint

The early 1770s were catastrophic for the Commonwealth's monetary system. Counterfeiting of small silver denominations had become so entrenched — much of it state-sponsored by Prussia — that Poniatowski's treasury was fighting a losing battle against its own currency. The dwugrosz issues of this period were repeatedly redesigned and restruck in attempts to stay ahead of Prussian forgeries that flooded Polish markets throughout the 1760s and into the 1770s.

The KM#Pn94 designation suggests pattern or provisional status for this specific die pairing, worth cross-referencing against Kopicki 2327 before attributing with confidence.
