recently purchased a coin that is different from the one in the catalog.

https://en.numista.com/catalogue/pieces16685.html

the seller bought the collection at an online auction and sold the coins one by one. he could not provide any details of the origin, but assured that the coin was genuine, like every other one in the collection.

here are its properties (in parentheses data from the catalog to compare)

Composition: most likely copper but maybe bronze (Brass).
Weight: 5.33 g (3.6 g)
Diameter: 22 mm (21 mm)
Thickness: 2 mm (1.47 mm)
Orientation: Coin alignment (Medal alignment)

For your sake I hope I'm wrong but that looks like a rather crude copy of a scarce coin.

that was my first thought.
but the coin looks old, has a nice patina, and really does not look like a crude copy.

It's the edge that bothers me the most. A struck coin would have sharp corners and be much more regular. Yours looks like a cast and reminds me a bit of the many fake pound coins we used to get in the UK. The fact that the metal looks about right is in its favour but the weight is way off as well.

Never encountered counterfeits of these coins, they are neither so popular nor so valuable.
OK. I will keep it. I suspect that they are much rarer than the originals.
Thanks a lot!
To me it's a huge red light when a seller cannot provide any details or info of what he is selling, but "assures" that everything's genuine.

​i agree with you. but I repeatedly bought other coins from this seller, and there were no problems with them. in fact, he simply buys the collections online and sells them one by one, so he can't explain the origins of each.
