In the upcoming spring auction of SINCONA AG a so far unknown coin type of Francesco IV. Gonzaga will be auctioned. It is a Ducato d'oro 1612 from the Mantua Mint, which has never been mentioned in the extensive literature on Italian numismatics to this day.
Lorenzo Bellesia, a specialist in Italian numismatics from San Marino, studied the piece and reported on it in detail in the journal Panorama Numismatico (issue 03/2019).
