Silver coin with hooked cross and 3 crowns. Swedish? [решено]

Hello everybody!
This is my first stop so I am quite excited. I have recently bought a small lot of coins and there is this little guy that has been quite tricky to identify so far.
It's a 0.3 g silver coins of 4.4 mm of diameter.
I am attaching a picture of the coin taken from the internet. It's exactly my type of coin, just in better condition, therefore I thought it could be easier to identify.
I think it could be Swedish because of the three crowns but I have honestly no idea.
What do you guys think?


Thanks a lot
