Ferdinand VI gold cob 2 Escudos ND (1747-56), Nuevo Reino mint, KM25, MS62 NGC. The double arcs on the potented cross and the "S" mintmark to the right of the shield allow to identify this as a Ferdinand VI issue. Much rarer than its Philip V counterpart, a choice specimen albeit with no apparent date.
Estimate: 1200-1500 USD
