Denár - II Ferdinand 1619-1637

Hello
I have doubts about authenticity. Weight and magnitude is pretty good.
It's too without patina and especially sharp features. When I visit the Kremnica Coin Museum -
I bet my coin is of good quality. Not rare or interesting for copies.
Please more experienced collectors for opinion.
Thank you
Ivan

​Everywhere the same shade of silver is too bright

I do not think it is fake, but it seems to be cleaned.
Perhaps geraltttt82 can help.
