Biafran pound
The Biafran pound was the currency of the breakaway Republic of Biafra between 1968 and 1970.

The first notes denominated in 5 shillings and £1 were introduced on January 29, 1968. A series of coins was issued in 1969; 3 pence, 6 pence, 1 shilling and shilling coins were minted, all made of aluminium. In February 1969, a second family of notes was issued in denominations of 5 and 10 shillings, £1, £5 and £10. Despite not being recognised as currency by the rest of the world when they were issued, the banknotes were afterwards sold as curios (typically at 2/6 (=0.125 GBP) for 1 pound notes in London philately/notaphily shops) and are now traded among banknote collectors at well above their original nominal value. 
Biafran pound was introduced three years after the civil war in Nigeria 

The most common note is the 1968 and 1969 1 pound notes, with the £10 note and all coins being rare.
