Silver "tumbaga" bar #C-284, 2454 grams, uncleaned. 8" x 3-3/4" x 5/8". Very neatly-molded, wide, flat ingot with smooth, uncleaned surfaces (one of very few examples), markings of owner(?) BRAo (a far less common marking on these bars), fineness IUCCxx (1220/2400 = 51% pure) and "R-code" RC on top but no visible tax seal (quinto), neat diagonal assayer's "bite" in corner, darkly toned all over with lots of green patina on bottom. From the "Tumbaga wreck," sunk ca. 1528 off Grand Bahama Island, pedigreed to the original Christie's auction of 1993 (lot #284), and plated in our new book The "Tumbaga" Saga (see lot #2789).
