KM-Pn66. Weight: 27 grams (AG .903). Erranously holdered as a regular issue. This is definetly the pattern issue. Struck on a 8 reales 1776, unkown mint. Date still visible. Strong lustre and must be among the finer that exists. Virtually perfect. Coveted Deep Cameo effect. This coin is a must have for any collector of important patterns, and world crowns alike. As far as we can see, this is the only specimen to get Deep Cameo. There are others that are in technical higher grade, yet this is probably one of the more visibly striking of the type.
