Costa Rica (1841-42) c/m 8 reales KM-19
"Republic Type I countermark over Colonial 8 Reales ND (1841) VF20 NGC, San Jose mint, KM-unl. (cf KM19 for this countermark over the earlier Charles III Mo 8 Reales). Base coin, choice Fine, countermark Very Fine. A Charles IIII 1791 Mo-FM 8 Reales pierced and countermarked with a radiant 6-pointed star in 7 mm circle per decree of November 22, 1841 under President Braulio Carrillo. This decree ordered the countermarking of all acceptable circulating silver coinage with the radiant 6-pointed star punch. Prior to the countermarking, the coins were applied a test mark to check their genuineness (located between "ET" and "IND" on the reverse in the present example) while the small removed silver plug was to compensate the cost of the operation. Naturally, this piercing was also intended to maintain these pierced coins in local circulation (a similar concept to the famous holey dollar issues of the West Indies). Rare as a type, and extremely rare over this host since by 1841 most of the milled Colonial issues (pillar or bust) had been replaced in circulation by the Republican Latin American coinages (the usual hosts found for this rare countermark). The only Mexico Charles IIII bust 8 Reales with the Carrillo countermark known to the cataloguer, and unlisted in all previous references, including Murillo's fairly recent and thorough checklist. This discovery coin should prove of the utmost interest to all collectors of the Costa Rican series."
