Last October the Reserve Bank of Australia (RBA) set in circulation more than 46 million $50 currency notes with an insignificant misspelling, but monumental in sheer scope. The value of the misprinted notes is said to be over $2.3 billion AUD, or $1.58 billion USD. Never before has a spelling mistake cost more than now. This is the first time in the history of the RBA that a monetary bill has been issued for public circulation with a misprint that reoccurs not once but thrice on each of the 46 million bills. It’s only ironic that the misspelled word is none other than “responsibility” which the imprint has penned thusly: “RESPONSIBILTY”.
