According to a press release dated 9 July 2012, the Bank of Ghana intends to enhance the security of the 50-cedi banknote (B149) by replacing the square holographic patch at lower right front with a cocoa pod printed in green-to-blue SPARK ink. The revised note is scheduled for introduction in early August 2012. The notes bear the signature of Vice President Kwesi Amissah-Arthur because when they were printed in June, he was the governor of the bank, having served from 1 October 2009 to 6 August 2012. Notes to be issued later will however bear the signature of the new governor, as of yet unnamed.
