Bogota, Colombia, 8 reales, 1821JF, with mintmark Ba, dot below and to right. Restrepo-157.4b; KM-C6. 24.13 grams. Lustrous UNC (very rare grade) with full central details (even rarer) but much debasement of the silver, dark copper color in center but lustrous silver color elsewhere. The Restrepo reference is a little confusing because it refers to this as "no dot in front of A," meaning no dot between the mintmark and assayer (which is the case here), but the dot that is supposed to be below the mintmark is actually placed to the right rather than directly under the A. (Estimate: $1500 - 2250)
