Cowrie Shell

Cowrie shells circulated as currency across much of Bronze Age China not by administrative decree but through organic trade adoption — their value rooted in scarcity, since Cypraea moneta and related species had to be imported from coastal regions far removed from the Shang heartland along the Yellow River. As the dynasty expanded and demand outpaced natural supply, the court began producing imitations in bone, bronze, and jade, a counterfeiting problem that was essentially state-sanctioned.

Hartill's designation of this as 1.1 — the opening entry in the entire Chinese cash series — reflects its foundational position in the numismatic record, not a specific mint attribution.
