Hell bank notes are a form of joss paper printed to resemble modern bank notes. Hell bank notes are not an official currency or legal tender anywhere in this world. They are intended to be burnt in Chinese ancestor veneration. Hell bank notes are known for their large denominations; ranging from $10;000 to several billions; and usually bear an image of the Jade Emperor; the presiding monarch of heaven in Daoism; with his signature (romanized as Yu Wong; or Yuk Wong) and the signature of Yanluo; King of Hell. There is usually an image of the Bank of Hell on the back of the bill.
