Watch List notes:

Potosi, Bolivia, cob 8 reales Royal (galano), 1715Y. S-P43a; KM-31; CT-875. 21.97 grams. Salvaged and not quite round but with clear Royal-die details (particularly the four fleurs around the denomination and pomegranate stops in legend, that side XF) and struck on a flat, broad flan (as opposed to the chunky regular issues), the pillars side well-detailed but the cross side corroded yet with full PHILIPPVS, die-match with Lazaro #259 (R2 rarity), attempted hole (or perhaps a filled one) at top of pillars side.
