Hello I have a coin, it's supposed to be made of silver. The sound is clear but I'm not an expert. If it touches bleach it makes oxidation. Diameter and weight are correct but I can't understand the thickness (more 2 than 3mm), it melts ice a little faster than steel coins... but how to be sure? Thank you

Please do not bleach it. You will ruin the coin value.

As long as the weight and size of the coin matches, it should be real including the ping test. The size is always more important than the weight. You can read why below.

And in the photo, it looks OK to me.

To seek for perfection, it is too painful and there is a very high price to pay. To seek for something comfortable is more easy. To seek for nothing is even more easy.

let in slide over a neodymium magnet if it silver it will be very easy to tell, if you don't have one weight (fine scales) (doesnt rule out everything but usally good enough) or XRF machine. yeah no bleach if it was high grade coin definitely not a good idea.

You should check the edge reeding, too. Fakes can often be recognized because they'll have rounded corners (where the edge meets the rims). The reeding should extend all the way from the top to bottom.

This coin only 19923 pieces were made. it is a rare coin.
here is our catalog page-
https://en.numista.com/catalogue/pieces15833.html
just look at Ebay.
a real one listed US$1900
fake ones -
two different dealers in china have many pieces to sell for $30.
it is a common fake.

Very bad fake. Compare with the original:
https://en.numista.com/catalogue/pieces5042.html (copper-nickel)
https://en.numista.com/catalogue/pieces80357.html (silver)
These were non-circulation presentation crowns, and should not look like your coin at all (weak strike, off-metal, overal matte appearance).
Avoid the dealer from whom you got them.
