Watch List notes:

Potosi, Bolivia, cob 8 reales, (1)6(1)7M, mintmark (and other P's) as O. S-P19; KM-10; CT-129. 27.10 grams. Crudely toned Fine+ with good full shield and cross (the latter slightly off-center), but it's the peripheral details that are most interesting: full 7 of date, bold sideways H, "ISOANNIA(RVM)," and mintmark as O placed right over a dot in the border. Pedigreed to the Ponterio auction of September 2005, with original lot-tag #774.
