I got a 5 groszy ( https://en.numista.com/catalogue/pieces18350.html )
but wondered why the picture shows one without "pols". Then I found out that it has the "F H" mintmark. That explains the pols! I found out something on the internet.
But how rare is it? My coin is not in a good condition, but how many of the "I B" coins (Mintage 1,9mil) were FH coins? Probably not rare but..
Here is my coin:


Weird. I found that most of them (until 1832) are "Pols" coins. The picture is pretty misleading? Should the 5 groszy page be split into two?
