Watch List notes:

Bogota, Colombia, gold cob 2 escudos, 1739 M, rare, ex-Luz (1752), ex-Sotheby's. Restrepo-M80.12 (unl); S-B26; KM-17.2; Cal-unl. 6.73 grams. Fascinating shipwreck gold cob with dark encrustation in crevices highlighting data like the king's name and ordinal and the fairly clear date, which is listed in Tauler (#301, without photo) but not in Restrepo, also with clear F mintmark to left and M assayer to right of full shield, the cross also full, XF with slightly rough surfaces from its time under the sea, neat pedigree to boot. From the Luz (1752), pedigreed to The Uruguayan Treasure of the River Plate (Sotheby's New York auction of March 1993), lot 117.
