Clémentine d’Orléans: Extraordinary Woman and Coin Collector

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.

Einer der Höhepunkte von Künker Auktion 395 ist eine spektakuläre Goldmedaille zu 110 Dukaten, die aus dem persönlichen Besitz von Fürst Ferdinand I. von Bulgarien stammt. Diese Medaille führt uns mitten hinein in eine Zeit, in der Bulgarien seine Wirtschaft modernisierte. Der Fürst packte dabei tatkräftig mit an. Und die Eisenbahn spielte dabei eine zentrale Rolle.

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.

What is money?

What exactly is money? It seems obvious. There are coins, banknotes, credit cards – wait, a credit card isn’t money, it’s just a means of transferring money, just like a cheque or an early modern bill of exchange. So what is it then? What functions must money fulfil in order to function as money?
