An interesting article (sorry if this a repost): “Reported in the journal Antiquity, archaeologists found a bronze foundry and various coin moulds, along with coin fragments and pieces of metal debris. An analysis of the finds revealed that the mint produced ‘spade coins’, named for the similarity to the gardening implement. Spade coins are the oldest form of commodity money used during the Zhou dynasty of China, and were used by the Zheng and surrounding regions until they were abolished by the first emperor of China in 221 BC.“ https://www.heritagedaily.com/2021/...-in-china-from-over-2500-years-ago/139852?amp
