Watch List notes:

Nesmith 11 for type/11; Cal-119; S-M2; KM-17. 11.94 grams. Despite corrosion on shield side rendering the legend there very soft, this dark-toned specimen has AU details, with just one other like it known to us (not atypical of Early Series coinage). From: "Golden Fleece wreck," sunk ca. 1550 in the northern Caribbean
