The Gnadenpfennig – An Object Between Decoration, Medal, and Coin
Gnadenpfennigs are an extremely rare category of numismatic objects. Künker is proud to offer nine lots in auction 418 on 29 January 2025 that are, or are likely to be, gnadenpfennigs. We explain the purpose of these issues and when they were created.
The Heidelberg Tun and Early Modern Winemaking
The most well-known symbol of the city of Heidelberg actually began as a sort of treasury: the Heidelberg Tun was built to accommodate the Palatinate’s tax revenue generated from winemaking. And then a Calvinist propagandist turned it into a tourist attraction. This is reflected in a medal that Künker will be auctioning on 29 September 2023.
The First Error Coins from Croatia
Croatian euro coins are still quite new: the popular tourist destination introduced the currency as recently as in January 2023. By now, the first Croatian coins have long found their way into Central European wallets – and there are also some error coins among them!
Charles I of Austria-Hungary: A Hapless Emperor Who Was Beatified
In the context of its Summer Auction Sales, Künker will offer the only gold coin of the last Austro-Hungarian Emperor that is available on the market. Johannes Nollé tells the story of this coin and its commissioner, who died in Madeira aged only 35.

Japan Mint: Hiroshima Branch
The Japan Mint doesn’t just produce beautiful circulation coins. It also manages the entire production process in-house, from the blank to the finished coin. This makes Japan one of the few countries that are completely self-sufficient when it comes to its circulation coins. We visited the branch of the Japan Mint in Hiroshima.
