I recently came across the story of Arent Van Bathmen a Mint Master who was executed in a cauldron of boiling oil for debasing silver coins. This happened in Deventer, Netherlands in 1434. I was trying to find what coins he debased but am having a hard time finding any silver coins made in that city or the nearby mint of Batenburg from 1400-1434. Does anyone more versed in this area know what would have been in circulation during this time frame?
