German Coin 18(??)

Hello,
I already posted this coin here before, but today I wanted to try something different.

It was found in the German region of North Rhine-Westphalia.

Its around 25mm in diameter and thin (around 1mm).
Unfortunately I ‎dont‎ have an accurate scale.

I still dont have a high resolution Camera, but I tried to take as detailed pictures as possible.
I also tried to point out everything i could see in MS Paint (very professional)
I think you can see the year 18(??) in the middle.
Thanks in advance


With MS Paint:

I know that its probably impossible to identify but if anyone wants to try you are welcome.

I still can not see much. Both from those pictures, and the others ...

They all look to have been taken indoors in artificial light;
can you make some more outside in daylight? Maybe more
letters will show up. Just a thought.
Your recent pictures, the second one, is that lower right
a V or N or M letter? Any others you can see?

Could not see the 18 numbers, but now rotated and in Grayscale I see them ...

but no others letters can be seen. So probably a coin with 18** in the middle,
which sadly rules out the coin in the link from your first post. Still looking.

This is the search I did, with 70 results ...

but nothing there (with central date). Maybe just not added, or created without
adding the diameter. Or may not be German. And so on ...

Such coins I put into a box. There is an entry at numista for unindentified coins. If someone in swap asking for one - I give them for free inside a swap.
