Watch List notes:

Guatemala, 4 reales, sun-over-mountains countermark (Type II, 1839) on obverse of a Cuzco, Peru, 4 reales, 1835 B, with El Salvador zigzag countermark (1835), very rare, NGC VF details / rev tooled, ex-O'Brien. cf KM-91. Fascinating piece that circulated in three different countries (Peru, then El Salvador, then Guatemala), the two countermarks both full and well detailed on the obverse of a well-toned host (reverse struck slightly off-center, with heavy old scratches near center), only the third we have seen of this combination (not listed in KM) and the first with this host date, also the only one listed in the NGC census. Pedigreed to the John O'Brien Collection (stated on label) and with his envelope.

Estimate: $1000 - $2000
