Silver "tumbaga" bar #M-148, 3841.9 grams, fineness IV@L (1550/2400), with two tax stamps of Charles I (Emperor Charles V), from the "Tumbaga wreck" (ca. 1528), ex-Armstrong Personal Collection, Garcia Plate. 10-1/2" x 4" x 3/4". A very smooth and tidy bar with just three marked places on top: two partial tax stamps (small, circular) near each end, one with ARO and the other with ROLV (of CAROLVS) visible; plus a cluster in the middle showing the fineness in three parts (IV, @ and L, the last one upside-down) with what look like small x's or s's in boxes above and below. The bottom of the bar is rougher and shows some gold color. One corner bears a sharply cut "bite" where the assayer removed silver for testing before marking the fineness. Pedigreed to the personal collection of conservator D.R. Armstrong, with his photo-certificate, and plated in the second edition of Tumbaga Saga (2018), by Agustin Garcia-Barneche.
