I’ve found this coin today, on a hill across the river from Loket castle in the Czech Republic, to add a bit of background info, in case it’s useful in identification.
I can’t recall exactly how old the castle is? Medieval for sure, perhaps starting from 1100s.
So the coin weighs exactly 1g. I know it’s copper for a few reasons, but I haven’t scraped it to be sure, which I normally do with scrap. It’s copper though I’m quite sure.
Very thin too. It’s not a perfect circle, which you could expect with these hammered coins. As for the size? I’ve lost my tape measure, but it should be on par with the spritzgroschen I found and posted about previously. So 22mm and the wider angle would be a mm or two wider than that it seems.
I’ve very gently washed it in pond water, to preserve the patina. I’ve heard some say I could add wax to this to bring out details. I won’t do that unless anyone suggests that may help bring out more details.
ive tried my best to get some good images. It may not seem amazing quality, but I have to say, it is in very good condition for something this age that is copper. It was found in woodland, normally on fields the crop chemicals waste copper away.
So I’ve taken a few varying pics, with a little light at a certain angle to try and bring any detail out. Also included images taken under a lens.
One side is decent. The other not so. But I’ve included it anyway.
Thought I could see a date at the bottom. After a closer look I’m not sure now. You Guys probably have a keener eye than me.
Im not holding out this is worth mega money. But it’s an obvious thing for me to question when I come by something like this. So I’d appreciate knowing if there was any significant value. Any details about this are appreciated.
I love the history side of all this. Something about the medieval era is very appealing to me. if that’s what it is. I’m familiar with other people on YouTube finding jettons in the UK which are copper. Apart from that, I’ve never seen a copper hammered coin.
So intuitively I sense this must be on the rarer side, which adds to my inquisitiveness.
ive included also an image of this next to the spritzgroschen for comparison. I’ll also add the thread about that, in case it further contributes in narrowing down what this may be.
The spritzgroschen was German. There was trade between this castle and Germany, a route in fact, that connected it and Germany. So the spritzgroschen was found within say 3 miles of this coin.
Here is the other thread:

this image below is under a loupe focusing on the best of the text
This was under the loupe again. This is what could be a date at the bottom. but I may have that wrong. First image shows this perhaps clearer I don’t know.

Here’s the other side. Again not amazing detail. or should I say it was hard to Capture in an image. I don’t mind posting more images if anyone thinks I can enhance the details. say with wax. I won’t do that unless instructed though .
Here is the size comparison against the spritzgroschen
Many thanks for any input.
