Sweden is a real place the last time I checked. Kidding.. Something looks off about your coin. Cast maybe?
Yeah. Sweden is real, been there. I'm also joking. That looks like a token, I agree with @muhfff. I've never seen anything like that before and I've looked at a lot of Swedish/Scandinavian coins. What makes you think it is Swedish? Oh, and just a friendly bit of advice. If this coin/token had been valuable, you would never want to hold it in your bare hands like the photos show. Valuable coins, or coins that might be valuable, should be held only be the rims. Steve
Seems that "Sagan om Husaby" is a movie (or play?) by Leif OLsson, see here. But pretty much everything about that production I have seen is in Swedish ...
