Proof or not?

I have this coin, the weight is 10g, and is clearly proof

According to Numista:

Nickel: (km#201) Weight 10g ( N#4249 )

Silver: (km#201a) Weight 15g ( N#177571 )

If my coin is really proof (looks like that), or, the proof version is missing in the catalog, or the Silver weight is wrong.

Does anyone have the same coin and looks like proof?

From Ucoin:

Should be easy to tell silver from Cu-Ni.  

So the Numista weight might be wrong

Maybe. Is yours silver?  The silver one in Numista has a Z (zilber) on the silver one.  Yours doesn't.

Indeed there is not.

Then should not even be considered proof
