Ferdinand VII gold 4 Escudos 1819 Mo-JJ AU58 NGC, Mexico City mint, KM146, Cal-162. Fully lustrous with slight high-point wear defining the grade and contained surface handling marks, thus quite attractive. The usually available date of this scarce type yet rare and desirable in this preservation. The cataloguer notes the AU50 example from the Rudman collection (Heritage Auctions 8/2015, lot 31397) hammering for $1,700.
