In July 2007 the Bank of Ghana introduced the third cedi-based currency, following a period of rampant inflation. This 1GH¢ stamp, equivalent to N¢10,000 in the second cedi currency, was issued to mark the centenary of the establishment of the Khilafat Ahmadiyya. The Khilafat, or Caliphate, is the institution of succession to a prophet in Islam. The Ahmadiyya movement follows the teaching of Mirza Ghulam Ahmad (1835-1908) who claimed that he was the promised redeemer of Islam (Mahdi) and Messiah. The Ahmadiyya Muslim Community was established in Ghana in 1921 and has funded a number of hospitals including the one depicted here in Daboase, Western Region.
