Carlos III gold 8 Escudos 1801/797 NG-M, KM58, FR-18, Onza-977. AU-55 NGC. "M" is for assayer Manuel Eusebio Sanchez. A very pleasant coin with little actual wear. The rarest date of this very rare type. The overdate is most apparent under the "8" digit where the "7" underneath can be clearly seen. Among the best specimens extant for the type, and much superior to the "La Onza" plate coin. Ex. Haberthuer (SBC 1/996, lot 2590).From The Isaac Rudman Collection of Guatemala Coins
