Watch List notes:

Neatly formed silver ingot, 1964 grams, about 98.5% fine, with stamps of the Amsterdam chamber of the VOC (Dutch East India Co.) and "jumping goat" assayer-mark of Otto and/or Wouter Buck, ex-Rooswijk (1739). 6-1/2" x 1-1/2" x 1-1/4". Typically very neatly cast in a perfectly rectangular mold with one end left open, resulting in a deep cavity in that end (now harboring dark orange encrustation) with small pieces chiseled off in its time to fine-tune the weight, one of the lateral sides graced at the other end with deeply stamped markings, smooth and corrosion-free surfaces throughout. From the Rooswijk (1739), with original plastic tag and certificate #A0377 from the salvagers.
