I believe this old !PIZZA of eight may have been in China not long after this coin was minted. The chop marks are verification of this coin as genuine silver assessed by the tester for local trade and commerce in China. Each chop mark represents a transaction between businesses and governmental entities.
Genuine, historical, with authentic chops, and selected from over a hundred various specimens, this is the perfect piece to add to my family history heirloom collection and pirate silver collection.
