Large silver bar, 453.7 oz troy (14 kg), marked with fineness IIUCC C X L II I (2343/2400), assayer ZALAZAR, manifest CXCII (192), and owner/shipper mark, very rare provenance, ex-Joanna (1682), ex-Bir. 16" x 4½" x 1½". This long ingot somewhat resembles the big Peruvian silver loaves from the Atocha of just 60 years earlier (and in fact recovered around the same time), with very similar markings, but of course with a later assayer cartouche that clearly says ZALAZAR, supposedly of the Oruro mine since there is no double-scoop "bite" for Potosí on the top (the edge too corroded to see a cylindrical version for Oruro). That cartouche appears right after the fineness (confirmed by XRF to be 98% fine silver), which appears upside down relative to the manifest number and owner/shipper "sigla" at the other end. Faded ghosts of other marks (mine/date and tax stamps) appear below center. The bottom and sides of this bar are quite eroded, and one side bears two drill holes from a modern assay. According to the salvors (who recovered this bar on February 23, 1984, as stated on the accompanying certificate), almost all the big silver bars from this wreck were melted, so this piece is accordingly rare; in fact, it is the only one we have seen (we sold it to Mark Bar in 1998). This piece may represent the only chance to own an ingot from the Joanna shipwreck. From the Joanna (1682), pedigreed to the Mark Bir Collection, with his certificate from 1998.
