Medieval silver coin identification?

Hello everyone and happy 2025!

I need help identifying this coin. I guess it is from 1500’s and Emperor Ferdinand I era, but I haven’t been able to find similar to this during my search. Diameter is 25 mm and weight 1,35 g.

Guessing lettering on reverse - George Arch Bishop C? Minden Verden D? Bremen Et Luneburg

Weight is close to value of half groschen or 1/48 thaler compared to imperial mint standard. Could be 2 grote as his bremen 4 grote were around 2.8 grams (https://numismaster.com/MC_180194).

Thank you. With your help I got a lead, and found several coins like this one from past auctions.

It looks like there's a date on the top, and this would be 1561. From other auctions I noticed that around 1562 the lettering changes, there is G IMP instead of G R IMP.

https://www.acsearch.info/search.html?id=2538589 1562 with G R IMP

https://www.acsearch.info/search.html?id=2644258 1562 with G IMP

However, I haven't found this coin from Numista database so far. Closest one I can find is this:

N#241698

Ewald Stange - Geld Und Munzgeschichte Des Bistums Minden

If you can read German in Gothic script, you can find his book on archive.org.

1.35 grams do not fit Fürstengroschen or Drier.

If you find entry which matches your coin, you might use that book as reference when adding new page to numista. Probably No 89 or 91.

I would suspect that variations exist with or without R in Ferdinand's title on 1562 coins.

Stange gives better explanation of reverse lettering.

Other source would be ‘Standard Catalog of German Coins 1501 to present’, but archive.org got only 1998 edition and 2011 edition on amazon is pricey.

I've read some books in Gothic in my own language, so that's not an issue. My German isn't the best, but I understand enough…

Number 89 is the only one I found to look exactly the same. My coin is quite thin (less than 1 mm) and worn, so it's not out of the realm of possibility to originally be around 2 grams. During a brief online search there was  one Fürstengroschen with 1,45 g weight. Also, the diameter is a match. The description in the book says there's a number “12” on the eagle crest, and that's also a match. That would be different with another denomination, if I understood correctly.

So, unless anyone can find another explanation, I'd say it's a match.

Yes, it was great to find exact meaning of the letters.

I will have a look soon when I have more time. I’ll probably take better pictures of it anyway.
