An auction to sell the largest collection of gold coins ever held in Poland.
Organized by an entity that does not specialize in numismatic trading, it went through without much notice in the fall of 2020.
It exhibited 55 coins, including many of the highest grade, including the crown ducat of Sigismund I the Old, or 50 1921 ducats (minted with the same stamp as 100 ducats).
