Greetings from Kyiv!
My topic is world coins by names. I collect in such a way as to collect one coin of different names (denominations, as well as recognizable among numismatists types of coins).
My collection includes coins cent, penny, filler, yen.. etc. Also separately consider grosz, groschen, silbergroschen, neugroschen...
My question, in fact, concerns this coin:

It is sometimes called simply groschen, but some numismatic sources refer to it as
Fürstengroschen.
Please tell, is it correct to call this coin Fürstengroschen (German "das Groschen von Fürstabt")? Is this a big mistake on my part?
Coin on my site (
https://www.dema-coins.com/2021/04/furstengroschen-coin-Princely-Abbey-of-Corvey.html) for a long time.. But only now did I have doubts (I had a discussion with a russian numismatist before the war...).
