In October 2018, the Reserve Bank of Australia (RBA) announced its plan to overhaul its currency to introduce new, more colorful notes. At the time, the reserve noted that the bills would come with new security measures and be made from durable material to last longer in the market. What they didn’t mention was the fact that the bills would also come with a spelling mistake.

This week, a few eagle-eyed Australians found a teeny, tiny spelling error on the $50 note. Oh, and the error was printed more than 46 million times.

On Australia’s new yellow $50 note, people can find the word “responsibility” spelled wrong.

This photo illustration shows the detail in Australia's state-of-the-art new 50 dollar banknote in Sydney on May 9, 2019, with a spelling mistake in the microprint of a speech by Australia's first woman parliamentarian Edith Cowan. - The yellow and green note came into circulation last October, but it took seven months for the public to notice "responsibility" was repeatedly misspelt in the text of Cowen's maiden speech to Australia's parliament in July 1921.

“It is a great responsibilty [sic] to be the only woman here, and I want to [emphasize] the necessity which exists for other women being here,” the bill reads. The quote, Business Insider explained, is an extract of a speech given by Australia's first female member of parliament as she entered office.

According to the RBA, they are aware of the issue, though there is nothing they can do about it. The $50 note, RBA confirmed, is the most widely circulated banknote in Australia.

Beyond the mistake, the new currency is still rather impressive. According to The Guardian, the currency is made with polymer, which increases both its durability and security. It also makes it easier to include brail and other features to help the vision-impaired, The Guardian reported. For example, the $50 note features four raised bumps to help people identify it.

As RBA added, it will be updating the text in the next print run of the $50 note. So, those that have their hands on one may want to hold onto it as it could become a collector’s item one day. Or, just go spend it and have a good laugh at the mistake.
