Watch List notes:

Costa Rica, 2 reales, Liberty head / ceiba tree counterstamp (Type III, 1845) on a Potosi, Bolivia, pillar 2 reales, Charles III, 1768 JR, extremely rare, NGC VF 20, c/s XF standard. KM-unl. Clear counterstamp (really a double countermark) with full head and tree and nearly full lettering, the host elements fully visible with contrasting toning around details. This counterstamp was supposed to be applied only to Spanish bust 2 reales in lower fineness ("pesetas españolas," per Article 1 of Decree LIII dated 13 November 1845), so higher-fineness pillar hosts are extremely rare. In fact, only five are known, of which this one is arguably the best, all the others being from the Richard Stuart collection: one Mexico dated 1754, two Lima dated 1757 and 1767, and one Potosí dated 1770 (see El resello de las pesetas españolas en Costa Rica [1845], published in 2018 by José Vargas Zamora, Manuel Chacón and Josué Sánchez Chaves). An exciting and very important coin for the Costa Rican specialist. (Thanks to Josué Sánchez Chaves for his assistance.) NGC #6447282-001.
