Watch List notes:

Dutch silver ingot, 877 grams, about 98.5% fine, no visible markings but probably Zeeland/Middelburg chamber of the VOC / Dutch East India Co., ex-Bredenhof (1753). 5-/2" x 1-3/4" x 1/2". Among the ingots recovered from this wreck were several like this one that lost significant weight to heavy corrosion and smoothing, but this one does bear some neat whitish encrustation on one side, naturally without any markings remaining. From the Bredenhof (1753), with original (small, generic) certificate from the salvors.
