Alright, I have got something, that is a bit peculiar and pretty environmentally damaged to put it mildly. I took some time to figure it out what it is myself, but looks like numista simply does not list that coin in its catalog.
Based of the reverse with something that resembles coat of arms of Philip IV the great (I even half see the collar of the Golden Fleece), I would think that it is a hammered copper coin of something between 1621-1665 minted (or rather hammered) for coinage of Spanish Netherlands. The interesting part if that I see a face facing right on the obverse, and that is quite unusual of copper coins of the supposed time period.
Alas, but letterings are hard to read, but they don't really much to `PHIL · IIII · D · G · HISP · ET · INDIAR · REX ·` I would expect to see there. My best guess so far is that's an ancient counterfeit coin made to look like a 2 sovereigns coin.
And yes, I know the coin condition is not top pop, hence this identification exercise is not a trivial one.
