Igho (manillas) translates directly from Edo to mean ‘money’, and as manillas were a form of exchange in the past, they were and are called Igho. Igho were the principal currency used within southern Nigeria during the Ọba dynasty. The British attempted to end the use of Igho with the Native Currency Proclamation of 1902, which prohibited the import of Igho with the aim of encouraging the use of coined money. However, Igho continued to be used, and in 1948 the British undertook a major recall dubbed ‘Operation Manilla’ to replace them with British West African currency. In contemporary Nigeria, images of Igho can be seen on the 100 naira banknote, illustrating their continued importance as a symbol of money and wealth.
