This is a second type of bronze cowrie I have seen a few times. This is flatter with less of an attempt to imitate an actual cowrie and is distinctive with 'grate' like appearance of the teeth. this is 24 x 16 x 2 mm at a mere .76 g.
I was the lucky winner in Kagin's Auction (Mar 2021) Lot# 4233. It consisted of 19 examples that were previously in the Nate S Shapiro Collection and displayed at the Detroit Money Museum. These were acquired before 1960 but were sold when the Museum closed (~1992). In ancient China cowrie seashells (Cypraea Moneta & C. Annulus) were so valuable that imitations were made to serve as money and grave items.
All of the number tags, unfortunately glued to most of the specimens in the museum collection, are a characteristic of all Charles Opitz collection pieces.
