EL SALVADOR. El Salvador - Mexico. 2 Reales, ND (1868). PCGS GOOD-04; Countermark: Fine Details.
KM-Unlisted. Type V countermark applied to the obverse of a 1773-Mo FM issue of Charles III with inverted mintmark and assayer's letter (cf. KM-88.1 & Cal-658 [for type]). Though the host coin is very well worn, it nevertheless retains enough detail to make identification rather easy, and with a countermark that still retains a solid appearance as well.
Estimate: $100 - $200
