Watch List notes:

Cuba (struck at the Philadelphia mint), specimen 20 pesos, 1915, unique, NGC SP 63, finest and only known in NGC and PCGS censuses. KM-21; Fr-1. Struck on a special planchet with higher rims and smoother fields, the resulting (prooflike) luster a treat to behold, perhaps missing a higher NGC grade for a couple tiny rim-nicks on the reverse but at least recognized for its specimen status. NGC #4499455-006.
