Watch List notes:

Lot of four Mexico City, Mexico, cob 1/2R, Philip III and IV, assayers P and not visible, three with partial dates that appear to be 1634/3, 1657 and 1658/7 (all rare). 6.12 grams total. This lot is a "sleeper," as all the coins are fairly nice (F-VF with good toning, no problems, good full crosses and generally good monograms) and three of them have visible dates that are just not quite clear enough to safely attribute 100%, the one undated piece struck off-center so that the full king's ordinal IIII is present. (Estimate: $250 - 375)
