Yen M3 - genuine or fake? [решено]

The coin countermaked with GIN and many chinese chopmarks.Weight 26.85g;D 38.8mm and Thickness 2,5mm. Any ideas (genuine? fake?)
Thank you

Gin (銀)?

That means "silver" in Japanese, so the coin is obviously made of silver. These were punched in the late 1800's and are really common as for the punch marks. Y#5.

Thank you

I don't concern about the chops and I know that GIN is silver, but my question concerns the coin itself. Is it genuine or the chops mark the fake just to deceive the collector?

It's real for sure.

But if you really want to be sure, check the density of the coin. Does it tarnish? How about the rotation?

Thank you for your prompt reply
Apparently the coin made of silver and it shows a natural well-patinated color. As to angular relationship between the obverse and reverse sides, some die rotation is obvious, which probably common for these coins.

Cool

I guess it's real then!
