PERU. Cob 4 Escudos, 1750-L R. Lima Mint. Ferdinand VI. PCGS AU-58. Fr-13; KM-A47; Cal-690. Weight: 13.5 gms. Exhibiting a bit of a die shift, this barely handled specimen nevertheless presents very little in the way of actual circulation and retains excellent overall detail. Tremendous quality for this lesser-seen fractional gold issue that tends not survive nearly as well as its larger brethren. From the David Sterling Collection.<p>Ex: La Luz shipwreck.
