China - Oval lead cowrie - Museum Gallery

Two unusual types of lead cowries came with the Charles Opitz collection. They were both removed from a limestone like substrate and were slightly different from one another. This is the smaller one with a flat top (bottom actually, cowrie teeth are under the shell), it's 27 x 22 x 12 mm and weighs 51.57 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.
