Watch List notes:

Cartagena, Colombia, cob 8 reales, 1628, assayer E below mintmark RN to left (RN-E), very rare, PCGS VF detail / saltwater damage, ex-Eldorado. Restrepo-M45.3; S-C3; CT-253; KM-3.4; CT-253. 26.07 grams. Bold and full inner details on both sides, the shield and denomination to left particularly nice (the RN-E to left visible but weaker), and the full cross-lions-castles on reverse doubled but well detailed and with bold full 1628 date in legend, darkly toned all over and with light surface pitting (note the good weight) as from an unspecified wreck. Pedigreed to the Eldorado collection (Stack's Bowers auction of January 2018), with original lot-tag #11019.
