Watch List notes:

Costa Rica (Central American Republic), 4 escudos, 1837E, rare, encapsulated NGC XF details / surface hairlines. KM-16. 13.3 gams. Lustrous and technically better than XF but with central flan-bulge that caused faster wear on high points and attracted bagmarks, parts of rims crude (as made). Pedigreed to our Auction #12, with original lot-tag #164.

Estimate: $5000
