The Bahraini Dinar was introduced as a currency in 1965, six years before Bahrain gained full independence; it replaced the Gulf Rupee at a rate of 10 rupees = 1 dinar. The Dinar is subdivided into 1,000 Fils (the singular form is also Fils); hence it is usually represented with three decimal places denoting the Fils. The 100 Fils (0.100 Dinar) coin is a relatively small denomination.
The 1965 issue coins were larger in diameter and were made from cupronickel (copper-nickel alloy); there was also commemorative silver coin of the same type in 1983. In 1992 this was changed to a slightly smaller bimetallic coin (copper-nickel centre and a brass outer ring) with a different design. Some silver 100 fils coins have also been issued as non-circulating legal tender.
Within a circle, the Coat of Arms of Bahrain. Around above, دولة البحرين (State of Bahrain, 1992-2001) or مملكة البحرين (Kingdom of Bahrain, 2002 and later). On the two sides, the date in Common Era (to the left) and Hijri year (to the right). Around below, STATE OF BAHRAIN (1992-2001) or KINGDOM OF BAHRAIN (2002 and later).
Commemorative coins of this denomination have also been issued, with a different obverse.
