Watch List notes:

Lima, Peru, 4 reales, Philip II, assayer R (tiny) to left (Rincon), motto as PL-VSV-LT, legends ISPA- and -N/NIARVM. S-L1; KM-10.1; CT-309. 12.42 grams. Choice inner details (AU-) and much bold legend, nicely toned but with traces of encrustation and very slight surface porosity. Interestingly there is no H at the beginning of (H)ISPA- (which also shows a serif-less A, unlike the other A's on the coin), and the small-R assayer-mark appears to be a punch for a 1-real die, all of which may be evidence of initial punches wearing out.

Estimate: $1500
