Watch List notes:

San Salvador, El Salvador, provisional 1 real, 1834, SAL with retrograde S, rare, NGC XF details / reverse tooled, ex-O'Brien. KM-18.5. Full and bold details with light toning all over, a few heavy scratches in field near center of reverse but still "way better than KM plate coin" (O'Brien), rare date and denomination (none offered publicly since 2009, also notably one of just two 1834 1R in the NGC census, the other being the previous lot, a different variety), unlisted in Jovel-Yonaka (Type A but with retrograde S on both sides), Villavicencio A1b. Pedigreed to the John O'Brien Collection (stated on label), with his envelope.

Estimate: $500 - $1000
