Found this on one of my beach hunts. Not sure what the composition is; possibly copper. No marks whatsoever. To small to be any kind of tent stake. My best guess would be a sand chess peice. Draw out board on sand to play. This peice maybe being a pawn? At any rate vary strange. Found it up in dry sand 30 yards from the water. No idea why someone would take something like this to the beach with them.
