3 Kreuzers - Francis I of Lorraine, as co-ruler Uncovered chest

Francis I ruled Hungary jointly with Maria Theresa following her pragmatic insistence on his coronation as co-regent — a constitutional arrangement the Hungarian Diet accepted only reluctantly, and which gave Francis little practical authority over domestic coinage policy. The "uncovered chest" designation distinguishes this die variant from related issues where the bust treatment differs, a distinction catalogued separately in Huszár precisely because Hungarian billon coinage of this period was struck at multiple facilities with inconsistent die preparation.

Billon quality varied considerably across the issue's fourteen-year run as the silver content in small-denomination Hungarian coinage was progressively debased to cover Seven Years' War expenditures.
