Bogota, Colombia, bust gold 4 escudos, Ferdinand VII (bust of Charles IV), 1818JF. Restrepo-126.1; CT-164; KM-72. 13.52 grams. AU details but polished and with four mount-marks on edge, still desirable as one of only two years of Ferdinand VII 4 escudos struck in Colombia (the other being 1819), hence a very tough type-coin.
Estimate: $1000-1500
