Silver "tumbaga" bar #M-61, 2119 grams, marked with fineness IV III L XXX (1380/2400) and two tax stamps, large area of exposed copper. About 9" x 4" x 3/8". Very neatly rectangular ingot (also quite flat) with bold fineness marking in center (with small x-shaped marks in boxes above and below, possibly the mark of the assayer), partial circular tax stamps near either end, diagonal “bite” in one corner, but most intriguing aspect is a large area of exposed pure copper, revealing how most “tumbaga” silver was created by hammering silver and copper together and therefore showing the true nature of “metal of Michoacan,” nicely toned all over, and important for never having been offered on the market before, as it was given out to an investor (Horner, via Lou Ullian) just after Armstrong’s conservation and recording. From the “Tumbaga wreck” (ca. 1528), and pedigreed to the David Horner collection.
