I'm very intrigued by it, even if it's outside my period of interest
Weight 0.28 g Diameter 14/15 mm (irregular round) Thickness 0.5 mm I also attach a drawing that shows what I see with good certainty. On the right side next to the wheel there seems to be another cross, like the one under the wheel. The other dial appears to show oblique lozenges. I don't want them to be just my suggestions I searched a lot and the coat of arms looks like a very simplified version of N#196366
Very similar. the coat of arms could be the same, but above it, in the center, there seems to be a stylized crown, preceded by a dotted C. The following letter, if it exists, is not readable. Following your indication I tried to do some extensive research. They gave no result. Assuming it's from some German state, I tried searching from 1500 to 1600 as the period, with "heller" or "pfenning" as the query. The search didn't even report the coins you reported.
Was it my mistake or something isn't working with the search?
the search query field needs a text, a part of text or a name to work.
“pfennig” or “heller” cannot work, these terms are not on a coin.
About your coin: I think it is a onesided pfennig and I think to recognize 65 as part of year over coat of arms, more likely 1565 than 1665. My search in catalog gives nothing and geison's results seem to help.
Alright. Did some digging. I'm fairly certain it's this coin here: N#129917 Archbishopric of Cologne (Koln) Hermann V von Wied (1515-1546) 1 Pfennig
If you do an image search in a web browser for “Hermann V von Wied coin” you can see it on a few sites. Looks like the side of your coin with the clearer image is actually the reverse.

It's a uniface coin and the reverse is just a struck thru to the other side and the wheel was on the wrong quadrant of the shield on that example. This coin is from a bit later.
