The variation of the apparent tenorite/cuprite ratio with depth was fitted to potential laws differing from one mint to another for A Coruna, Burgos, Cordoba, Cuenca, Granada, Madrid, Trujillo, Segovia, Sevilla and Valladolid coins. Electrochemical data permitted to detect the changes in the composition (with lowering of the silver content) and manufacturing technique (from hammer to mill) occurring in this historical period.Financial support from the MICIN Projects CTQ2014-53736-C3-1-P and CTQ2014-53736-C3-2-P, which are also supported with ERDF funds, is gratefully acknowledged.
