Cayon, Adolfo, Clemente Cayon and Juan Cayon, Las Monedas Espanolas del Tremis al Euro, del 411 a Nuestros Dias, Madrid, 2005, 1465 pages, hardcover in two volumes. A huge much-improved replacement for the old Cayon and Castan. This incarnation begins with the Suevii in 411, covers the pre-Visigoth, Visigoth and Islamic coinages of Spain before getting into the more traditional medieval coinage of the previous volume. Each type is photographed. For Islamic coinage, prices in euros are given for many mints for each type, including north African mints for dynasties like the Muwahhids and others that spanned the Mediterranean and the Strait of Gibraltar. A great overall reference for Spanish coins, set of 2 volumes.
