The only material additions to this system of Alfonso the Wise were briefly—
- The coronados, an innovation of his successor, Sancho IV. (1284-95), who, in 1286, introduced them as = 1 old dinero. They subsequently appear as cornados.
In the Cortes of Toledo their relation to the novenes was thus determined:—
6 coronados = 10 novenes = 1 maravedi de moneda vieja (= Burgaleses).
- The series of gold coins initiated by Alfonso XI. (1302-50).
It was in the reign of this latter King that the general movement of adoption of gold coinage first touched Spain. The earliest gold coins were Alfonso's doblas, subsequently known as castellanos. The weight of this coin has been variously assigned as 48 to a mark or 50 or 51.
Taking the tale of 50 to the mark, the weight per piece would be 92 4⁄25 grms. (= 4.60090 grms.) of 23 3⁄4 quilates fine (= .989 fine).
Pedro I. made gold doblas of the weight of 90 grs., and Page 324 this endured till the days of John I., 1379-90, who preserved the same weight but lowered the standard. Under Henry III. the standard of 23 3⁄4 quilates was again restored. For the movement of the gold coins subsequent to Ferdinand and Isabella, see the Table.
- The silver real first appears under Pedro I., 1350-69. It was issued at a tale of 66 to a mark, and 11 dineros 4 grs. fine.
Under Henry II. of Castile, 1369-79, these reals undergo extraordinary debasement, the standard being reduced to .279, .129, .060, and so on; but a recovery took place under his successor, John I., 1379-90, who returned to the standard of Pedro I., substituting for the debased real his
