The pictures are so dark, it's tough to make out any detail.
It looks like it's a Hungary Denar from between 1500-1600, but I can't get more specific than that.

The pictures are the two sides of the same coin. I glanced through the listings in the catalog and could not find one that matched. I found only one that had a Crown, but it was quite different. The coin is copper or bronze. The denars seem to be primarily silver.
I get that the two pictures together are front and back. But you posted two sets of pictures that are clearly different coins. The original coin has cuts in it while the second one does not. There are also two different backs.
It's possible the coin is made out of billon. If it was a poor alloy, it may have had much more copper than silver.

Then this definitely looks correct for your coin. The back side is an eagle with it's wings spread.
This would be the correct orientation of the coin:
