Here is the provided documentation:

I just got one in a swap (coarse?) and I had one in my collection (no idea). So I've analyzed both of them here:

My two coins both have 104 ridges, so I'm still not sure which variant I have!
If anybody has one with a ridge count different to 104, please send me an image, or better, if you have it in double, then let's just swap it?
Thanks in advance
Ole
