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 bronze 1 Fils coin was only issued in 1965 and 1966; it no longer circulates.
In 1983, a silver one Fils coin was issued as part of a commemorative set (i.e. it is non-circulating legal tender).
