定義

• Originally a Spanish silver coin issued under Alfonso X of Castile (1252-1284), and struck principally at To- ledo. It bears a crowned bust of the king, and on the reverse a gateway of three towers. In the fourteenth century it began to appear made of billon and of much in- ferior workmanship, and it seems to have been discontinued early in the sixteenth century.
