Watch List notes:

Silver "tumbaga" bar #M-38, 5 lb 2-1/2 oz av., marked with partial fineness and assayer B~Vo, from the "Tumbaga wreck" (ca. 1528). 6-3/4" x 3" x 1". Typical "flat brick" but atypical in bearing the marks on its rounder "bottom" (as cast), that surface pitted from corrosion but still with clear assayer but any tax stamps no longer visible, nicely toned all over, crude assayer's "bite" in one corner. From the "Tumbaga wreck," sunk ca. 1528 off Grand Bahama Island, with Sedwick photo-certificate.

Estimate: $4000 - 6000
