Watch List notes:

Small, flat Peruvian gold bar #35, 410 grams, marked with fineness XXIII: (23.5K) and assayer MOSQVERA and foundry CVZCO, from the Santa Margarita (1622). 4" x 1-1/4" x 3/8". Very attractive bar for its size and clear markings, including bold fineness in center (two incuse X's followed by III in one box and : in another) along with a faintly inscribed fineness (temporary marking), two full assayer cartouches and six circular tax stamps, PLUS a foundry cartouche for Cuzco at one end, the other end with diagonally sheared assayer's "bite," nice coral encrustation in crevices, very similar to the Queen's Museum specimen (a 1981 exhibit in New York City). Of all the assayer marks on Atocha and Santa Margarita gold bars, MOSQVERA appears to be the rarest. From the Santa Margarita (1622), with Fisher photo-certificate #35-M-80.

Estimate: $30000 - 60000
