1 Ducat - Dan I jointly with Mircea I Type Ia

Dan I ruled jointly with his uncle Mircea — later called "the Great" — in the early 1380s, a co-reign arrangement that produced one of the shortest and rarest issuing periods in Wallachian numismatic history. The "Ducat" designation here is nominal; these small silver pieces circulated in a principality sandwiched between competing Hungarian and Ottoman pressures, their monetary system largely derivative of Hungarian and Bulgarian models.
