Hungary's hyperinflation I believe was the worst ever at least up until that time and if it was not the very worst in history, any that "beat" it could not have beaten it by much since at its peak, the value of all paper money (not sure about coins) I recall reading was 60 US cents.
But how could this be true? Of course, coins being made of any metal whatsoever would have some intrinsic value, easily exceeding perhaps many tens of thousands of dollars, even if they were made of aluminum or tin. But even paper money can be burnt and the energy content of all that paper would again be worth much more than 60 cents -- people I would guess were in fact burning the money.
The cost of printing the money should not exceed its value -- the ink, paper, labor and distribution are significant costs that should establish a bottom for the value of the currency.
