Between 1971 and 1985, Guinea used the Syli (meaning elephant). It was subdivided into 100 cauris (shells, formerly used as currency). The syli was available in banknotes and coins. The first set of banknotes were launched in 1971 in denominations of 10, 25, 50 and 100 sylis, and the second set was printed in 1980, featuring different colours and additional denominations of 1, 2, 5 and 500 sylis.
Coins were available in 50 cauris, 1, 2 and 5 sylis.
In 1985, the syli was replaced by the Guinean Franc.
