Watch List notes:

Guanajuato, Mexico, cap-and-rays 8 reales, 1851PF, very rare provenance. 25.86 grams. Solid coin (surface corrosion only) with full (VF) details, toned with some big dark patches, common coin but very rare for its very obscure origin, presumably the ship that gave its name to the reef where it sank (the same reef that claimed the famous Geldermalsen of 1752). The ship's namesake was a Dutch hero in the Anglo-Dutch wars of the mid-1600s. With World Treasure Books certificate. Recovered from: Luitenant Admiraal Stellingwerf, sunk in 1857 off Singapore / Indonesia

Estimate: $100 - 200
