$1.6 Billion in $50 Bills in Australia Were Printed With a Typo

Australia's $50 banknote is filled with details; there are so many of them that it's hard to spot the typo that slipped onto the face of the bill. But if you know where to look, you'll see the spelling error that the treasury failed to catch before printing it on millions of pieces of currency.

According to CNN, the $50 bill, worth about $34.90 in U.S money, debuted in October 2018. It features Edith Cowan, Australia's first female member of parliament, with her inaugural speech to the Western Australian Parliament typed out in microprint above her shoulder. The words are hard to read, but in the zoomed-in image below you can see the word that's supposed to read responsibility in the second line is mistakenly spelled responsibilty. The bill also features innovative security features, such as holographic design elements, but the typo snuck by unnoticed.

The misspelled word was printed on 400 million banknotes, 46 million of which are currently in circulation. Altogether, the misprinted currency in circulation totals A$2.3 billion, or US$1.6 billion.

Australia's treasury plans to keep the bills in circulation and correct the error when the next batch of $50 banknotes is printed sometime in the next few months. Other typos of this scale have resulted in major consequences: In 1962, a missing hyphen in some computer code caused a satellite to explode, costing NASA $80 million.
