50 000 000 - Hell Bank Note

Hell Bank Notes are not currency in any monetary sense — they are votive offerings burned at Chinese funerals and ancestral ceremonies so the deceased can spend the money in the afterlife. The Míng Dū Bank (冥都 literally means "underworld capital") exists purely as a ritual fiction, giving the notes a superficial legitimacy that mirrors real banknotes closely enough to satisfy the symbolic requirement.

Hong Kong became the dominant production center for these items, exported worldwide to diaspora communities. Collectors pick them up as curios, but their catalog value is negligible — production runs are large and they were never scarce by design.
