Watch List notes:

Santiago, Chile, gold bust 8 escudos, Ferdinand VI, 1750 J, ICG AU50, ex-Luz, ex-Sotheby's. KM-3; Cal-822. Slabbed by a second-tier service before NGC and PCGS came to a consensus on shipwreck gold coins, this bold and highly lustrous specimen is likely a candidate for MS 61 today, except that first one would have to remove lots of fascinating tan and pink sea-growth from around the details, the modicum of surface marks almost all from handling before sinking, desirable as labeled with its original Sotheby's lot number. ICG #3533150108. From the Luz (1752), pedigreed to Sotheby's (New York) Uruguayan Treasure of the River Plate auction of March 1993, lot 404 (stated on label).
($2500-3750)
