Watch List notes:

Lot of five Potosi, Bolivia, cob 2 reales, Philip III, assayer Q/C, rare. S-P17; KM-8. 32.96 grams total. Important study lot of all different dies, some with multiple over-assayers (all clearly visible), F-VF (one pitted) with full shields and crosses, mostly toned, one with tiny hole at bottom of cross. While the majority of these are simply Q/C, there appear to be some C/Q and at least one Q/C/Q, reflecting the interplay between assayers Francisco Calderon and Agustin de la Quadra in the last year of the latter's life in 1616 ("la mejoria de la muerte," according to Jorge Proctor). In truth each of the coins in this lot could stand on its own, but we think they should remain together, as they have with the consignor, for further study and comparison with other examples. One pedigreed to our Auction #13, with original lot-tag #1192 (also pedigreed to our Auction #4, with original lot-tag #703, and to the Cayon auction of December 11-12, 2006, with original lot-tag #5378).
