Denga - Ivan Vasilievich ND

One interesting fact about the Denga coin is that it was used as a form of currency during the reign of Ivan Vasilievich in the Principality of Yaroslavl, which was a region in the north of medieval Russia. The coin was made of silver and had a standardized design, which was unusual for that time period. This suggests that the Principality of Yaroslavl had a relatively advanced economy and monetary system compared to other regions of medieval Russia.
