659. Potosí, Bolivia, cob 8 reales, Philip III, assayer Q. S-P17; 662. Potosí, Bolivia, cob 8 reales, 1645T. S-P30; KM-19a; CT-492.
KM-10; CT-124. 26.78 grams. Broad flan with good crown, bold P-Q, full shield and cross, Fine+ with patchy brown toning. Estimate: $200-$300.
25.82 grams. Oval flan with thick edge (in contrast to salvaged coins that are typically thin), good full shield and cross, bold date except for last digit, VF with toning on fields, hairline edge-split. While still rare as a dated cob of the 1640s, this date comes around more often than any other from 1640 to 1648. It’s slightly lower weight (uncorroded) hints at the raging scandal at the time. Estimate: $400-$600.
660. Potosí, Bolivia, cob 8 reales, Philip III, assayer Q. S-P17;
KM-10; CT-124. 26.46 grams. Richly old-toned VF+ with bold P-Q, nice full shield and (doubled cross). Pedigreed to the Jess Peters auction of June 1970, lot #1141. Estimate: $200-$300.
663. Potosí, Bolivia, cob 8 reales, Philip IV, assayer Z, no countermark, rare. S-P34; KM-19a. 25.49 grams. Broad flan with choice
full cross-lions-castles and shield, bold P-Z, flat peripheries, toned AXF, a coin with moderate rarity on three levels: for the assayer, for its lack of a countermark and for being non-salvage (also note the low weight, indicative of the scandal that broke just after this coin was issued). Estimate: $500-$750.

S-P26; KM-19a;
