Ok...I think I have it.
I believe it is a Spanish 8 maravedies coin, from the era of Philip III (1598-1621) or Philip IV (1605-1665)
It appears that even though some of the coins were minted before the year shown on the coin, sometimes they were overstruck with new dates, markings, etc.
Here is a page with a lot of coins that are in much better shape, but have similar markings:

Here is a coin with similar markings from that page. Note the way the date looks (1641 according to the website), and the overstrike of the "VIII". You have the Roman numeral VIII on yours, though the last "I" is pretty messed up. Kinda interesting how there was no real quality control....they just would overstrike the coin any place they saw fit.
Here is another similar one:
I am curious also...where was this found? Is it made of copper? How deep underground was it? You might want to do a very careful search of that area if there is any possibility of more of these being there (well, it is ALWAYS possible haha).
Wow...amazing what info I find when I decide to do research for people here LOL!
Anyway....MY GOD!
