The Carl Ludwig House on the Raxalpe and tourism in Austria

On 22 September 2026, Künker will auction a ‘Raxalpentaler’ from the Wenzel collection. Only 100 specimens of this coin are said to have been minted, making this piece one of the rarest Austrian commemorative coins. But is it actually a commemorative coin?

Cleaning, Patina, Verdigris etc.: Which Errors Affect the Price of a Coin? – Part 2

The price of a coin does not only depend on its rarity and quality. In the second part of our overview we will talk about wear and tear, cleaning and the consequences of environmental processes.

Bulgaria, Prince Ferdinand I and the Railroad

One of the highlights of Künker’s auction 395 is a spectacular gold medal with a weight of 110 ductats. It was the personal property of Prince Ferdinand I. of Bulgaria. This medal takes us back into a period when Bulgaria modernized its economy. And the railroad system played a major role in this.

L. E. Bruun: A Collector in His Time

On the occasion of the upcoming auction of the second part of the Bruun Collection, Ursula Kampmann set out again to explore the story of the person behind this collection on behalf of Stack’s. This time, she took a close look at Bruun’s career as a collector. Read on to learn about the coin trade and the world of collecting before the Second World War.

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.

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.

Good to know

How do commemorative coins differ from collector coins?

For a long time, I thought the term ‘collector coin’ was a made-up term coined by uninformed mints. A collector coin is, in fact, by no means a commemorative coin.
