Watch List notes:

Contemporary counterfeit (made to look like a Mexico City, Mexico, bust 8 escudos, Ferdinand VII but with bust of Charles IV, 1819JJ) struck over a Bogota, Colombia, 16 pesos, 1849RS. 26.39 grams. Fascinating coin struck from what at first appear to be official dies but the details don't match (wrong bust for the date and mint), and closer inspection reveals elements of the later under-coin, particularly on the edge (reeded) and reverse, where the under-coin's 1849 date is visible at the bottom. Almost certainly this coin was related to debasement problems at the early Republican mints of Colombia and Ecuador, inasmuch as the locals gave preference to the higher-fineness colonial gold coins, this specimen clearly circulated nevertheless (XF with weak bust).

Estimate: $1000 - 1500
