I've used image search of the catalogue for this coin but I can't find it. The nearest is this:
N#94906
Is the date 768 or 1768? I think it's probably 1768 but not certain:
Diameter 1.5 cm
Possibly Lippe.
Added: Lippe-Detmold https://www.acsearch.info/search.html?id=12731018
That's what I thought from my image search, but I can't find a coin that matches, unless I'm missing something.
It's in KM but with no photo: https://www.ngccoin.com/price-guide/world/german-states-lippe-detmold-mattier-km-189-1766-1768-cuid-1141454-duid-1338309
You might look on MA-shops for an example. Always a good research site for German coins.
Edit: I had not read your first post closely enough. I see that the Numista listing has no legend on one side, but the acsearch link looks like a better match.
It looks like the 1769 type: https://www.ngccoin.com/price-guide/world/german-states-lippe-detmold-mattier-km-196-1769-cuid-1138710-duid-1338310 but dated 1768.
Might need for a membver with a good Germany catalog to comment.
