The term 'Money Shell' is a reference to the COWRIE, a type of sea snail that was historically used as a form of currency in many parts of the world. The COWRIE has a distinctive shell with a glossy exterior and a flat underside, which made it easy to carry and store. It was widely used in Africa, Asia, and the Pacific Islands, and was even accepted as a form of payment in some parts of Europe. The COWRIE is still used today in some parts of the world as a symbol of wealth and prosperity.
