1.50 grams. Restrepo-Lasser believed this issue to be unique, and the example known to them was plated in Restrepo, Restrepo-Lasser, Calicó, and Krause-Mishler. This additional example is far finer and makes for a published population of just two specimens. The surfaces are frosty and nicely toned, dark gray with multicolored highlights. The obverse is well centered, while the reverse is ideally misaligned to the left to permit the definitive S assayer to be visible right of the cross. A very important rarity for specialists, from the tiny and short-lived production run at the newly reopened Cartagena mint for a short period in 1655 and (illegally) for perhaps a year and a half afterwards. From the Eldorado Collection of Colombian and Ecuadorian Coins.
