Silver "tumbaga" bar #M-152, 3615 grams, marked with owner/assayer YB13, owner/assayer INo/DeBCA and fineness iUiiiio (1400/2400, 58%), plus partial tax stamp, ex-"Tumbaga wreck" (ca. 1528), Armstrong plate, Tumbaga Saga plate. 11-1/2" x 3-1/2" x 5/8". This fairly flat and tidy ingot has several interesting features: First, the owner/assayer mark INo/DeBCA on top is 100% full (even shows the tilde or wavy line above the last two letters), with partial circular tax stamp below that. Second, the rounder bottom of the bar shows two small incuse boxes with previous owner/assayer YB13 and fineness, the two separate assays also represented by diagonal "bites" in two different corners of the bar. And finally, the top of the bar shows lots of little bubble-pits that appear to contain pieces of partially un-melted items, a testament to the hasty and abrupt nature of the conquest of Michoacan where this silver originated. From the "Tumbaga wreck" (ca. 1528), with photo-certificate, the owner marking plated on page 39 of Doug Armstrong's Tumbaga Silver for Emperor Charles V of the Holy Roman Empire (1993) and also plated on page 115 of Agustin Garcia-Barneche's Tumbaga Saga (second edition, 2018). Recovered from: "Tumbaga wreck," sunk ca. 1528 off Grand Bahama Island
