The Suffering of Leiden – A Siege During the Dutch Revolt

The third part of the Beuth Collection that Künker offers in Auction 420 contains many historically interesting emergency and siege coins. They were issued by the Dutch towns besieged by Spain during the 80 Years' War. One of these towns was Leiden, which to this day commemorates the end of the siege every year with a festival.

Joachimsthal and the Reformation

On 29 January 2025, Künker will auction a series of valuable Renaissance medals. They feature biblical topics and were minted in the region of Joachimsthal to spread the teachings of the Reformation. Johannes Mathesius, the author of Luther’s Table Talk, may have been at the origin of some of the motifs.
