Coins were introduced in 1949 in denominations of 1, 5, 10, 20, 50 and 100 fils. The first issue of 1 fils were mistakenly minted with the denomination given as “1 fil”. 20 fils coins were minted until 1965, with 25 fils introduced in 1968 and ¼ dinar coins in 1970. The 1 fils coin was last minted in 1985. In 1996, smaller ¼ dinar coins were introduced alongside ½ and 1 dinar coins.
This is a 500 fils coin, or ½ Dinar. In geometry, a heptagon is a polygon with seven sides and seven angles. In a regular heptagon, in which all sides and all angles are equal, the sides meet at an angle of 5π/7 radians, 128.5714286 degrees.
