Hi

 

Maybe someone knows what is it?
I have no idea it is original or fake.

Ø30 mm

It looks like  https://en.numista.com/catalogue/pieces49411.html  But my coin has 2 more letters - "MD".

looks real

corrections welcome

That's all good. But it is interesting, Krause catalog knows about existence of this coin? What's its KM-number?
I couldn't find this coin in Standard Catalog of World Coins 1601-1700 (4ed).

Krause is not complete or accurate

And that is the million dollar answer   .  Krause is great for beginners, but once you start collecting a particular type seriously, it falls way too short.   The Polish coinage is too complex for Krause to properly categorize.  There are too many variations and Kopicki's Ilustrowany Skorowidz Pieniêdzy Polskich i z Polska Zwiazanych is probably the standard and it spans numerous volumes!  The other book is Gumowski's Handbuch der Polnischen Numismatik.  Referring to Kopicki:

Kopicki-1766

Thank you!!!
