One of the very rare varieties of late Sigismund III trojaks.
In 1607, the Kraków mint discontinues the issuance of trojaks. However, these are already different coins - smaller, minted according to the new minting ordinance - containing less silver. But despite the large scale of their production, Kraków cares about the quality of the stamps produced. Errors on them are encountered very rarely. The present trojak is one of the few exceptions.
A variation with an error in the reverse legend - REGE instead of the correct abreviation of the word"kingdoms", i.e. REGN.
