Notes:
Still contains the 'bead.' Made of bone ash.
At the end of the fire assay process, a small "button" of gold and silver alloyed with lead remains. This button is then heated in a cupel to drive off the lead. What remains, then, is a button of silver and gold.
Found on Sandy Beach by Kevin Weir in 1977.
