I find it curious they wouldn't give a Close up

even if it was a real Spanish coin, and dug there it doesn't prove much.
other then someone dropped or chucked it in the swamp.
if real & not a Fantasy Piece, would look something like this depending on date

Spain. Phillip IV of Spain. AE 8 Maravedis (cob coin) 1652. AVF
Cool find though even if it's a recent pub token for an 8 Cent shot.
I thought these guys were Treasure Hunters Though ? Not Spook hunters

acting like signals disappearing was Hocus-Pocus

we all know if you break a Halo or change position of a Flat object, or piece of wire,
it will disappear at least for awhile.
Signals disappearing are not spooks moving things around
all the B.S. aside, I wish I could be there

the Swamp diving reminded me of Sweet Arrow Lake Mud Hunting 15 Years ago
..... Good Times
