Ferdinand and Isabella (ND 1474 - 1504) - 1 silver Real minted in Seville. The coin appears to retain an original patina with very little, is well struck and little clipping and still showing full legends. Mass is 3.05 g and 25mm.
The Catholic Monarchs Ferdinand II & Isabella I were highly influential on the history of Spain and the world. Ferdinand was king of Aragon while Isabella was the Queen of Castile. Their union in marriage, and as shared monarchs of Spain, essentially united the kingdoms into a unified Spain although the two were actually governed separately. The symbolism of this unity is expressed on both sides of this coin. The obverse, shown in reverse order here, shows their Coat of Arms, what's not seen on the coin is their motto "'tanto monta', ("as much one as the other"). the outer legend here is : FERNANDVS ET A ELISABET:D
The reverse features the symbol of Ferdinand II as a double yoke of the type used for oxen, as in two monarchs working together. For Isabella we see a bundle of arrows, not dissimilar to a fasces. The outer legend is: + REX : ET : REGINA : CAST : LEGION : ARAGO : the meaning being KING and Queen of Castile and Aragon.
