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 500 Fils (0.500 Dinar) coin is the largest circulating denomination.
Five Dinar coins (as well as larger denominations) have only been issued as non-circulating legal tender and are struck in precious metals. This first commemorative coin of the Five Dinar denomination celebrates the 25th Anniversary of the World Wildlife Fund. It is struck in sterling silver (0.925) in proof grade and contains 0.5781 oz.
