Silver "tumbaga" bar M-25, 2175 grams, marked with serial RC, assayer B~Vo, fineness I9CCCCLXX (1970/2400) and one partial tax stamp, ex-"Tumbaga Wreck" (ca. 1528). 7" x 3" x 3/4". A very neatly cast "half brick" of relatively high-grade silver (XRF tested at about 90% silver, despite its marked fineness of about 82%), with wavy top surface but fairly smooth bottom exhibiting all the markings (circular tax stamp with [CARO]LVS visible, serial and assayer in separate boxes above fineness in small characters inside four boxes), neatly chiseled diagonal "assayer's bite" in one corner, lightly toned and with a minimum of surface corrosion, in short a very desirable size and quality for this popular earliest-known Spanish colonial wreck. From the "Tumbaga Wreck" (ca. 1528), with original Daniel Frank Sedwick photo-certificate and Armstrong book Tumbaga Silver for Emperor Charles V of the Holy Roman Empire (1993).
