 The Gideon Gono series of 2004 carried the signature of the incumbent Reserve Bank governor, Dr. Gideon Gono and consisted of only one denomination of the first dollar ($500).This was the last series of regular banknotes of the first dollar, as hyperinflation forced all regular banknotes series out of use, although remaining legal tender theoretically until 21 August 2006.The Standard Chartered series was a series of emergency bearer cheques issued by the Standard Chartered Bank (hence the title on the top of these cheques) and the Cargill Cotton Group.
