Watch List notes:

Potosi, Bolivia, bust 8 reales, Charles III, 1774JR, encapsulated NGC MS 64 PL (unique as PL). KM-55; CT-974. Among the many gorgeous specimens of this date from a 1970s hoard, which go up to MS 66 in the NGC census, this appears the one and only example designated PL (for prooflike), referring to its cameo-like (near frosty) details and mirrorlike fields, the latter (at least on the obverse) with evidence of special die-polishing (supported by various struck-through fibers) but also a couple very minor (natural) flaws, no marks, with incipient toning in hair only. NGC #3641333-002. (Estimate: $3500 - 5000)
