Some currencies, such as the German Papiermark, the Hungarian pengő, the first Turkish lira, and the second and third Zimbabwean dollars, had banknotes with this number in the denomination.
Sorry - I had some formatting problems and my guessed answer wound up in the subject line. I think the expected answer is a trillion since it is so unique but my wiki searches said something different:Turk lira: topped out at 1,5,10,20 10^6 (max 20 million)Ger Papiermark: went up to 1 10^9, ...100 10^9 (max 100 billion)Pengo: 100 million to 100 quintillion (10^20!)Zimbabwe: topped out at 100 trillion. Also, for Germany I was confused as milliard seemed to mean other than a billion (10^9) as they were both issued) All this is a result of hyperinflation.
