Second edition of these tables for converting various levels of purity of silver which, to facilitate the levying of royalties in Mexico, show the net value of all quantities of purity of silver.  In 1772 the coinage was reformed and a Pragmatic decreed by Charles III, dated 29 May 1772, introduced new regulations for minting silver, the fineness of the silver in coins being lowered to 0,902.   Francisco de Fagoaga was a member of the powerful Fagoaga family;  “if any one family could lay claim to the leadership of the Mexican silver-mining industry it was the Fagoagas.   For three generations, throughout the entire span of the eighteenth century they participated in many of the industry’s greatest enterprises” (D.A. Brading, Miners and merchants in Bourbon Mexico, 1763-1810, p. 173).   “Francisco de Fagoaga, a wealthy silver banker, who then operated the trading firm in conjunction with his mining interests . . .” (idem p. 120).   The book first appeared in 1729, and the licences are dated 1729.
