Silver Circulation Through 16th�18th Century Spain

Estimating global fluxes of precious metals is key to understandingearly monetary systems. This work adds silver (Ag) to the metals (Pband Cu) used so far to trace the provenance of coinage throughvariations in isotopic abundances. Silver, copper, and lead isotopeswere measured in 91 coins from the East Mediterranean Antiquityand Roman world, medieval western Europe, 16th�18th centurySpain, Mexico, and the Andes and show a great potential for provenancestudies. Pre-1492 European silver can be distinguished fromMexican and Andean metal. European silver dominated Spanish coinageuntil Philip III, but had, 80 y later after the reign of Philip V, beenflushed from the monetary mass and replaced by Mexican silver.
