Watch List notes:

Gold "oro corriente" cut piece with choice full "f" stamp for Ferdinand V of Spain, 80.10 grams, from an unidentified early 1500s wreck in the Caribbean. 1-5/8" x 1/2" x 1/2". Rectangular edge-cut of a thick gold disk of undetermined fineness (probably around 20K), with three sides (all but the outer edge) crystalline in texture (broken, not sliced), granular bottom but smooth top marked with partial circular tax stamp and full "f" in box, believed to be one of the earliest markings known on "oro corriente" pieces (used in place of coins in areas where coins were not yet made or available), with small spots of black but otherwise fairly clean. From an unidentified early 1500s wreck in the Caribbean.
