Watch List notes:

Lima, Peru, cob 4 reales, Philip II, assayer X below mintmark P to right, HISPANIARVM with H, very rare. S-L3; KM-11; Cal-497. 13.52 grams. Exceptionally broad flan with 100% full and sharp details including the all-important P-X to right, faintly toned in crevices, a few minor edge-splits but overall a contender for finest known, certainly the best we have seen, no worse than AU for grade. An interesting side note is that the obverse die for this coin is the same one used for the known oD/X examples (which are actually more common), showing HISPANIARVM with H, as opposed to other known assayer X pieces without the H.
