Australia’s Triple M radio station Thursday posted a close-up photo of the note on its Instagram account, showing the error.
The mistake — which would be hard to spot with the naked eye — is in microprint beside Edith Cowan, the first female member of an Australian parliament. The microprint next to her features excerpts from her maiden speech to the Western Australia state Parliament.
The RBA said it became aware of the issue last December, and the spelling would be corrected for the next print run.
“These banknotes are legal tender and can continue to be used as normal. It does not affect their validity and functionality in any way,” a spokeswoman said in a statement to CNN. “We have reviewed our processes to remove the likelihood of such an error occurring in the future.”
David Unaipon, Australia’s first published Aboriginal author, is also pictured on the notes alongside excerpts of Unaipon’s book “Legendary Tales of the Australian Aborigines.”
An RBA release last October described the $50 note as the “most popular note,” accounting for nearly half of the total value of all those in circulation.
The RBA has already released new versions of the $5 and $10 banknotes, and an upgraded $20 note is expected later this year.
