So coin looks copper to me but i don't see a copper one listed here and could only find a bronze one

Dimensions are a match but.

How to verify?

Kraus calls it bronze,

the other possibility is a gold proof .

"Bronze" is not a rigorous term. If this alloy is 95%/5% it might be called bronze , and you might not be able to distinguish it from 100% copper.

​True. Case in point, all USA "copper" pennies from 1864 to 1982 are really bronze (95% Cu, 5% tin and zinc).

Thanks for the wisdom :)
