Medellin, Colombia, copper pattern 5 decimos, 1889, doubled lettering and date, rare. Restrepo-24 var (p. 253). 9.83 grams. A second example of this rare pattern (missing in Eldorado) but with the date and lettering doubled on the die (perhaps a later test), lighter in color and slightly higher grade (AU, also with crude rims) but with light scratches on obverse and traces of verdigris.
