These are cool. I have a couple denominations from this shipwreck. My Wife had bought them for incredible prices. I can post some pics after all my minions are off to school.
This 8 Reales coin came from the dutch VOC ship Rooswijck , paid 147 pound sterling, unslabbed but with COA . condition: about Uncirculated. I like the so called tulip edge. 99% of all shipwreck coins went on board in uncirculated condition, if they were out of their wooden cases, near iron or copper objects on the seafloor during a couple of hundred years,they suffered, even to the point of complete dissolving. On the other hand if they survived in their cotton bags in their original wooden cases they often submerge in like new condition.

Does anyone know if cast gold or silver submerged prior to the first atomic blasts has value to those making high end instrumentation or electronics? For some reason, I'm thinking silver does as well as ferrous metal. I learned about this from the guy who invented the PRISM rebreather and trains seals, smugglers, underwater welders/arc gougers etc in how to use them.
Google the ships name El Cazador then select how a ship wreck changed the shape of America . Sorry my cut and paste on the pad isn't cooperating . There's a write up by Don West
