Sounds like you have a Kennedy half dollar with a Lincoln counterstamp, or a Lincoln Cent with a Kennedy counterstamp. These are create outside of the mint, but have value as a curiosity or to counterstamp collectors.
I have 50 1983 cent coins "pennies" with the outline of all 50 states counter stamped on them, bought them real cheap a few years ago. Also I have about 10 or so with Kennedy counter stamped on them. I didn't buy them to flip for a profit, I just think they were a neat addition to my Lincoln collection.
It's a well-known novelty coin, usually sold with a card listing "10 Amazing Coincidences" between Lincoln and JFK (e.g., both presidents' last names have 7 letters and both assassins' full names have 15 letters) that implies that the two men are linked supranaturally.
