The Somali shilling (sign: Sh.So.; shilin; شلن; scellino; ISO 4217: SOS) is the official currency of Somalia. It is subdivided into 100 senti (Somali, also سنت), cents (English) or centesimi (Italian).
The shilling has been the currency of parts of Somalia since 1921, when the East African shilling was introduced to the former British Somaliland protectorate. Following independence in 1960, the somalo of Italian Somaliland and the East African shilling (which were equal in value) were replaced at par in 1962 by the Somali shilling. Names used for the denominations were cent (singular: centesimo; plural: centesimi) and سنت (plural: سنتيمات) together with shilling (singular: scellino; plural: scellini) and شلن.
On 15 October 1962, the Banca Nazionale Somala (National Bank of Somalia) issued notes denominated as 5, 10, 20 and 100 scellini/shillings. In 1975, the Bankiga Qaranka Soomaaliyeed (Somali National Bank) introduced notes for 5, 10, 20 and 100 shilin/shillings. These were followed in 1978 by notes of the same denominations issued by the Bankiga Dhexe Ee Soomaaliya (Central Bank of Somalia). 50 shilin/shillings notes were introduced in 1983, followed by 500 shilin/shillings in 1989 and 1000 shilin/shillings in 1990. Also in 1990 there was an attempt to reform the currency at 100 to 1, with new banknotes of 20 and 50 new shilin prepared for the redenomination.
In terms of coins, the East African shilling and somalo initially circulated. In 1967, coins were issued in the name of the Somali Republic in denominations of 5, 10 and 50 cents/centesimi and 1 shilling/scellino. In 1976, when the Somali names for the denominations were introduced, coins were issued in the name of the Somali Democratic Republic for 5, 10 and 50 senti and 1 shilling.
