Watch List notes:

Bogota, Colombia, cob 4 reales, Philip IV, assayer not visible (style of Pinto, ca. 1630), with crowned-L countermark on cross, unique and important, ex-Maravillas. Restrepo-M35.3. 12.80 grams. At first glance this appears to be the usual Potosi shield-type cob with countermark applied in 1649-52 (of which there were thousands on this wreck alone); but a closer look at the details in the shield (full but off-center) and cross (full but doubled) reveals that this is actually a COLOMBIAN cob, the first and only specimen on record with such a countermark and therefore of extreme importance to cob collectors of both Potosi AND Colombia. The countermark is full, and the coin is relatively corrosion-free (F/VF details), with sediment in crevices, two edge-splits. From the Maravillas (1656), with Marex tag #91-4R-0425. (Estimate: $1500 - 3000)
