Iridium..
Possibly dating from 5000 BC..
Found on a mask washed up on a beach in Florida?
Possibly from a Spanish shipwreck that looted Brazil...?
Could this be from a Death Mask from an ancient burial..?
an ancient burial with a death mask covering the face of an extraterrestrial being sent to give the Aztecs knowledge of metallurgy...?
Could this be evidence of extraterrestrial beings...?
Sent to seed the Earth...?
Or just a piece of aluminum foil left over from the 10th Annual Treasure Hunters Cookout where AARC was cooking off some of his dredge spoils....

smokey playing with AARC's foil afterwards, because, well, thats what cats do....
aquanaut bets foil mask will float, tosses it in the water and everyone toasts and cheers as it floats away.......
the rest is history...
