Watch List notes:

Potosi, Bolivia, cob 8 reales Royal, 1649 O, very rare. S-P35; KM-R19b; Cal-1390. 26.26 grams. Remarkably broad flan that extends well past the outer borders, with full legends (king's name as PHELIPVS per the period) and nearly full crown, full interiors (good cross, weaker shield), toned Fine with traces of gilding-removal, significantly without hole but with small, tangential segment broken off in its time, perhaps to regulate the weight (or evidence of some other type of pendant use instead of a hole), as it has been seen before on at least one other example (Guttag/Yriarte/Gibbs specimen, UBS Auction 70, March 2007, lot 65, similar weight), a die-match with Lazaro #110 (rated RX, meaning no more than three known, but our count is now four with this newly discovered example), first we have offered of this date.
($3000-4500)
