Besides, the produce both of Guanajuato and Sombrerete, is given separately in the Table of Produce, as taken from official records.
I annex a General Table of the total Coinage of all the Mints of Mexico, including that of the Capital, from the year 1733, when it was first placed under the direction of the Government, and returns of the annual coinage regularly kept.
By this it will appear, that the sum of 1,435,658,611 dollars has been registered as the produce of the mines of Mexico in ninety-three years, (from 1733 to June 1826.)
The work of Baron Humboldt enables me to add from Registers, which, but for his researches, would now have ceased to exist, (since not even the Mexican Government has been enabled to annex them to its official statements of the Mint Returns,) 272,514,825 dollars more, as the registered coinage of the Mint of Mexico from 1690 to 1733, with which year the present table commences.
This gives a produce of 1,708,173,436 dollars in a hundred and thirty-six years, and proves both the constancy of the producing powers of the country, and the moderation of Baron Humboldt's calculations with regard to them, since he estimated the amount of silver raised from the Mines of Mexico in 1803, (from the Conquest in 1521,) at 1,767,952,000 dollars, or, 2,027,952,000 dollars, if one seventh were added to the Official Returns for unregistered silver.
