Republic gold 20 Colones 1899 MS65 NGC, San Jose mint, KM141. Gem Uncirculated with full mint bloom and handsomely patinated with only a few trivial contact marks, as expected for the lofty grade. The key date of this uncommon three-year type and the single example certified in MS65 by either grading service, also the finest seen by the cataloguer and clearly an extreme condition rarity in this superb quality.
