Please help with coin info

Any help would be great.

It's Russian.

I think it's either this: https://en.numista.com/catalogue/pieces8229.html

or this: https://en.numista.com/catalogue/pieces22423.html

because on your picture you can't see what denomination it is, but you can see the star to the left of where it would be. So it's not the 1/4 or 1/2 kopek coins.

A size and weight of your coin would tell you which one it is =]

Many thanks for you help.

Weight = 28.3g and is 38mm?

Thanks again.
