1500s or earlier Spanish coins, pirate treasure of 4 pieces, metal detector finds from an old Spanish harbor dock area. Cleaned by the metal detectorist. KING PHILIP II, 1558 - 1598 KING PHILIP II ’CATHOLIC KINGS’ coins. These rare coins date from the “Reconquest” and into the unification period. Reconquest was a period in the history of the Iberian Peninsula of about 780 years between the Muslim / Umayyad conquest of Hispania in 711, the expansion of the Christian kingdoms throughout Hispania, and the fall of the Nasrid kingdom of Granada in 1492. The term Catholic Monarchs or Catholic Kings refers to Queen Isabella I of Castile and King Ferdinand II of Aragon, whose marriage (in 1469) and joint rule marked the unification of Spain. Isabella was eighteen years old and Ferdinand a year younger. It is generally accepted by most scholars that the unification of Spain is traced back to the marriage of Ferdinand and Isabella. Their greatest achievement was the financing of Columbus, who discovered the New World. Isabella died in 1504 and Ferdinand died in 1516.
