Watch List notes:

Bogota, Colombia, copper pattern (gold 16 pesos), 1847, NGC AU 50 BN. Restrepo-24 (p. 171); KM-Pn6. While indeed a pattern (for a date that preceded the adopted type (Restrepo Type 213), this should also be considered a specimen strike, as the rims are higher and the surfaces smoother, with more definition to the strike than for just a test coin, yet in this case with a little bit of wear on the highest points and with tiny marks from less-than-careful handling, also dark brown and with only muted luster. NGC #4668518-006.
