What buried treasures have you found doing field work?

Many years ago we found a piece of a UFO, or at least an airplane. Aluminum, half round in two different planes. Had to be the edge of a flying saucer. Remained a mystery for a long time, until one day I looked at a fertilizer spreader, and realized it was one of the flingers. Much less exciting.

Turned up a wood stove once with the plow. And a bunch of other stuff, no one seems to know that there was ever a farmstead there. Lots of history already long gone and forgotten.

Buddy had some clearing done on 60 acres, nothing said until working it down he was told there is a disc out there upside down flat to the ground sort of in the middle.
