Help With Unknown Coin [решено]

I found this coin in my grandads house in Poland. I have no backstory on how he got the coin. He let me have it and I have tried identifying it on my own but have no luck. If anyone here could give me at least some information on this coin I would be very happy

Thank You :)

I think it's some kind of imitation of a Thaler from Teschen of Elisabeth Lucretia. Minted in 1643 by mintmaster Hans Lorenz.

Oh so by imitation you mean it is not the real coin?

Welcome to Numista. Providing weight, diameter and composition would be helpful in addition to the photo. This is what I could find with some of the same wording and possibly lead you in the right direction. I don't believe it is a coin per se because there is no date or denomination so it is considered a medallion.

It's Polish from Elisabeth Lucretia as above.

It could be anything though, from a rare copper in her early reign to a 5 Thaler. (It's not a 5 thaler)

The reason it is most probably an imitation is because they are incredibly rare. I've seen one in my lifetime, in a Danish vault. (belonging to an auction house not me)

There's a couple on numista from her late reign, if you type 'lucretia' in you'll find them.

I also found these from her late reign.

If I had to punt a guess, I'd say perhaps some jeton or low denomination, or a weird imitation. I say weird, as it'd be a pretty weird thing to counterfeit/fake.

Thanks for the reply. Apparently it should be silver but from what I have seen it is too light and does not pass the magnet test so it is definitely not silver.

It doesn't really look silver anyway.... How big/heavy is it?

7cm in diameter and weighs 17g
