The banknote with the highest denomination in history: Hungary's 100 quintillion pengő from 1946.
In numismatics, there are numerous records, and one of them is a banknote recorded in the „Guinness Book of Records“, which is the banknote with the highest denomination ever issued – 100 quintillion pengő (10²⁰). This exceptional, almost surreal denomination of the banknote was issued in 1946 in Hungary.
