That coin was a lot easier to find than I thought it would be, given the damage. I got lucky and found it straight away. It's a 3 groschen from Poland. I can't read a date on it, but it's from sometime in the period 1500-1700 I haven't found a picture of an exact match on CoinArchives, but this one is the closest:

Your top picture is the reverse; it's almost completely upside down, but you can see the two shields, the words GROS ARG and the denomination III at the top. I'm not sure if the prominent "10" is a number (part of the date) or part of the inscription.
The lower picture is the obverse. If you rotate it about 120 degrees clockwise, you can see the portrait of the King of Poland facing right, wearing a "Shakespearean" frilly collar (quite different to the plain collar on the one I've pictured) and a crown on his head. You can't read his name, but part of his titles are visible: REX P M D.
Not sure of the value; if it's from before 1601, it's not in the commonly available world coin catalogues. Poorest condition 1600's specimens range from $5 to $35. Your pics are fuzzy to judge the grade properly, but we can tell that the coin has been holed; that will reduce the value to a collector.
