Completely Unknown To Me - Need Help | Rechenpfennig

It's not a coin, it's a "rechenpfennig" (counting token), also known as a jeton, from Nuremberg. Obverse reads "HANNS KRAVWINCKEL IN NVR"; Hans Krauwinkel II was token-master in Nuremberg in the period 1586 to 1635.
On the reverse, "GOTES SEGEN MACHT REICH" is Old German for "God's blessing makes riches", a quote from the book of Proverbs.

Do a forum search for "Nuremberg rechenpfennig" and you'll see a few others that have been posted here for ID, like the one in this thread. Unfortunately, the site I linked to in that old thread is now defunct, but this page on UK Detector Finds Database is just as informative.

I have no idea how valuable they are; being non-coins, they're not listed in the catalogues. I don't think it's too rare or valuable; I paid AU$18 for a very similar one in near-Unc condition last year from a local dealer.

Not that valuable as they are quite common, but very interesting, I've got a group of jettons I'm half way through identifying from all over Germany and France
