Question: how many state do we have in biafra

title: Biafra
text: The bank was first located in Enugu , but due to the ongoing war , the bank was relocated several times . Biafra attempted to finance the war through foreign exchange . After Nigeria announced their currency would no longer be legal tender ( to make way for a new currency ) , this effort increased . After the announcement , tons of Nigerian bank notes were transported in an effort to acquire foreign exchange . The currency of Biafra had been the Nigerian pound , until the Bank of Biafra started printing out its own notes , the Biafran pound . The new currency went public on 28 January 1968 , and the Nigerian pound was not accepted as an exchange unit . The first issue of the bank notes included only 5 shillings notes and 1 pound notes . The Bank of Nigeria exchanged only 30 pounds for an individual and 300 pounds for enterprises in the second half of 1968 .
