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 250 Fils (0.250 Dinar) coin is the second-largest regular denomination after the 500 fils (one dinar and larger denominations have only been issued as commemoratives and non-circulating legal tender).
However, it has not been used for regular circulating coins - the only issue of a 250 fils coin was a FAO commemorative in 1969, with the same design repeated in 1983 for another commemorative issue. The latter was also issued in silver. |
