Spelling mistakes found on Australia's new 50 dollar note

The Reserve Bank of Australia is reeling after a local radio station posted a photograph on social media highlighting an embarrassing spelling blunder on the country's new 50 dollar note in early May.

Uploaded to Twitter, Triple M shared the image was sent in by a listener, showing the word "responsibility" misspelt three times as "responsibilty."

Although the note has been in circulation since October last year, it hadn't previously been detected because the writing appears in 'reverse text' which is only detectable via microscope.

According to rare currency dealer Jim Noble from Noble Numismatics, this is the first time the Reserve Bank of Australia has ever made a "typo" on any currency.
