Large silver ingot 728 from Potosí, Class Factor 1.0, 76 lb 10.24 oz troy, marked with mint/date Po1621, fineness IUU CCC L XXX (2380/2400) and assayer Mexía cartouche, owner/shipper marks, tax stamps, and manifest number IIIUDXXXIIII (3534), ex-Atocha (1622). A premium example with completely uncorroded top showing very bold markings all over, particularly the large owners' "siglas" at either end, also with a V for silvermaster de Vreder, with the other markings more toward the center where a double-scoop assayer's "bite" appears below the clear date I6ZI, which is this bar's rarest feature, along with the clear, multi-line assayer cartouche following the fineness, one of the best we have handled, excellent for display. From the Atocha (1622), with Fisher photo-certificate S728.
