Florin - János Zsigmond and Izabella

Izabella Jagiellon reclaimed the Transylvanian throne in 1556 after years of forced exile in Poland — the result of Habsburg pressure that had compelled her to surrender the crown to Ferdinand I in 1551. This florin, struck two years after her return, was issued jointly in her name and that of her son János Zsigmond, then a minor, a dynastic pairing that reinforced legitimacy through both maternal regency and hereditary claim simultaneously.

The Resch reference spanning five catalog numbers reflects documented die variation across the 1558 output rather than distinct types.
