Mexico - 1740/30 Silver 4 Reales "Hollandia" Shipwreck Coin

KM-94 Silver 4 Reales 1740/30 in XF condition for this strike but has been immersed in salt water and the surface is rough and porous. No papers or certificate with this and we honestly don't know if any were issued. Has a nice/clear date and nearly all of the legends are visible. The date appears to be a 40 over a 30 but we can only see traces of a 3, actually looks like double 4's. Anyway, this is a decent looking coin with all major details visible. A scarce 4 Reales denomination rarely found on any shipwrecks from this era. A very historic and important coin available here at a low opening bid.
