For sharing fascinating artifacts and replicas

I love these little dolphins. They're from the era when the first coins were being invented and it seems like people hadn't settled on "round, please."

They're also cast bronze, which ended up being unusual for the Greek and later Roman world. The vast majority of ancient coins were hammered by hand using dies and heated metal disks. Coins in China, however, were made by casting for thousands of years. China also had some interesting ideas about money (ant money, spade money) before they settled on the traditional "round with square hole" design.
