Hungary’s one hundred quintillion banknote, the odd denominations of Burma’s numerology money, Britain’s hundred million pound banknote, and money origami.

The dictator of Burma created new currency denominations based on numerologically auspicious figures. Imagine trying to make change with 15, 35, 45, and 90 kyat notes!

The Hungarian “hundred billion b.-pengő” is perhaps the largest number to ever appear on a banknote.

If you’re tired of spending cash, you could fold it up instead.

Deep in the vaults of the Bank of England are the titans, banknotes worth a hundred million pounds each.
