There’s so much to love about inflated currency, and Hungary’s Korona and Pengo are wonderful examples of the genre. After WWI, things went wrong at the treaty table and the value of the Korona began to drop, triggering the printing of money with more and more zeros.
When the Korona became virtually worthless — and there was no more room for zeros on the bill — it was replaced by the Pengo.
The Pengo held the fort for a time, but after WWII, which ended even worse for Hungary, its value plummeted and the numbers took off again.
I will say this for Hungary, no matter how worthless the money became, it remained beautiful.
