 Another type of superstition involving cash coins is to have them buried with a corpse for good luck as well as to provide protection to the grave or tomb from evil spirits, although this tradition doesn't exclusively involve cash coins as early 20th century silver coins bearing the face of Yuan Shikai, known outside of China as "Fatman" dollars (袁大頭, "yuán dà tóu"), have also been used for this purpose.In Bali it is believed that dolls made from cash coins (or "Uang kèpèng") strung together by cotton threads would guarantee that all the organs and body parts of the deceased will be in the right place during their reincarnation.The Tlingit people of the United States of America and Canada used Chinese cash coins for their body armour which they believed would protect them from knife attacks and bullets.
