If you would be so kind!
Coin size (diameter and weight) could be useful in attribution, but I think your top coin is a Hungarian Denar from the reign of Rudolf (1592 AD)
No idea on the second one, can’t make out much detail from the pictures. Hope others can add more.

Thanks you guys are the best! The silver coin is thin and smaller than a dime. The bronze coin is thicker about the size of a nickel..
