Philip II gold Cob 4 Escudos ND (1556-1598) S-C/D VF25 NGC, Seville mint, Cay-4142. An intriguing overassayer, with the "C" clearly repunched over the "D." The strike is typical for the type and the time spent in circulation has resulted in few post-strike imperfections beyond the wear to the central devices.
Estimate: 800-1200 USD
