Shell money is a form of currency that has been used for centuries in many parts of the world. It is made from shells, usually from mollusks, and is often used as a form of jewelry or decoration. The three most common types of shell money are WAMPUM, peag, and COWRIE. WAMPUM is a type of shell money made from the shells of the quahog clam, which is native to the Atlantic coast of North America. Peag is a type of shell money made from the shells of the whelk, which is found in the waters of the Atlantic Ocean and the Caribbean Sea. COWRIE is a type of shell money made from the shells of the cowry, which is found in the Indian Ocean and the Pacific Ocean.
