Nigerian naira
On November 12, 2014, the Central Bank of Nigeria issued a special 100 naira note to celebrate the 100 years of Nigeria's existence. The notes are similar to its regular ones with the portrait of Chief Obafemi Awolowo on front, but is redesigned to include a new color style. It has the text "One Nigeria, Great Promise" in microprinting and  a quickresponse code (QRC) which when scanned leads users to a website about Nigeria's history on the back.
