Large silver bar 387 from Potosí, 79 lb 1.76 oz troy (28.4 kg), marked with date 16Z1, fineness IIUCCCLX (2360/2400), manifest number IIIIUDCXXVII (4627), A-series mark, and tax stamps, Class Factor 0.8, ex-Atocha (1622), ex-Morse. 13¾" x 5" x 3". Neatly cast "loaf" with bold markings of manifest number and fineness (including Mexía assayer cartouche) above and below central circular tax stamps flanking the typical double-scoop assayer's "bite," with clear PoI6ZI mine/date cartouche (mentioned on certificate) below and left of the manifest, two more tax stamps closer to each end, also with bold A (from an official letter punch) to left of fineness that denotes an undocumented series of bars without owner/shipper marks (most also lacking silvermaster V), which some researchers believe were used to pay taxes to the crown and therefore were not marked to be reunited with their owners upon arrival in Spain. From the Atocha (1622), with original Fisher photo-certificate 85A-S387, pedigreed to the J.M. Morse III Collection.
