Watch List notes:

Seville, Spain, gold cob 8 escudos, Philip IV [sic], 1668 (M?), NGC AU 58, finest and only example in NGC census, ex-J.O.B., ex-Rudman. Cal-1007; KM-168.2. 26.58 grams. Very boldly struck, with 100% full shield showing distinctively abbreviated upper half (just one castle and lion), also full cross-and-tressure, mostly flat peripheries (hence no visible mintmark, assayer nor denomination) except for a bold full 68 of the date, the final digit made from punching a second 0 below an existing 0 on a 1660-dated reverse die, confirmed by the presence of -PVS of Philip's name in the obverse legend (also a die-match with known 1660 coins showing assayer A/C on obverse), more likely an oversight than an intentionally posthumous issue, the boldness of the central strike enhanced by dark encrustation in crevices. Pedigreed to the J.O.B. Collection (stated on label) and to the Isaac Rudman Collection, Plate Coin #151a in Tauler's Oro Macuquino (2011), with collector's tag.
