Watch List notes:

Mexico City, Mexico, 2 reales, Charles-Joanna, "Early Series," assayer F/P to right, mintmark M to left (oMo-oF/Po), extremely rare. Nesmith-15 for type; CT-110 type; S-M3. 6.65 grams. HISPANIARVM variety. Shield side with oMo-oF/Po, pillars side with left-leaning rhomboid panel, single o's outside pillars and on corners. A choice example for this very elusive assayer, believed to have struck coins for only a few months between assayers P and G (presumably in the year 1541, but in any case just before the changeover to "Late Series" in 1542), with only about 26 coins in four denominations still extant. Broad flan with full and bold legends, AU- with nice toning, hairline edge-cracks.
