With a monetary system influenced by both a Muslim current and a European one, the reign of Isabel and Fernando will try to unify the monetary types for both Castile and Aragon. The Castilian was established as the unit for gold and the double Castilian was called excellent due to the magnificent purity of its metal, superior to that of other similar European coins. They repeat, in their different mints, the facing busts of the monarchs on the obverse and the eagle of Saint John and shield on the reverse. This coin had multiples of 2, 4, 10 and 20 and a divisor, the excellent half. This provision was intended to unify the monetary system while regulating the operation of the different mints.
