Watch List notes:

Bogota, Colombia, 1/4 real, 1828 R.S./R.R., unique, NGC MS 65 with gold WINGS sticker, finest known in NGC census, ex-Lissner. Restrepo-unl (cf 146.2); KM-unl (85.2 for type). Fully detailed strike and smooth fields, no wear or marks at all, with light toning over luster, the rims a bit crude (as made) but ostensibly the finest known by far for the date, hammered in Lissner for $7500 (described as "an absolute gem"), in which the cataloger mentioned an over-assayer (overlooked by NGC) but proposed an illogical under-assayer RU (which was a Popayan assayer) as opposed to RR (the Bogota assayer in 1828). Until and unless other examples are identified, this piece can be considered unique and probably missing in even the most advanced collections. NGC #3831525-045. Pedigreed to the R.L. Lissner collection (stated on label).
