Watch List notes:

Mexico City, Mexico, cob 8 reales, 1610/07 F, extremely rare, NGC AU details / cleaned. S-M17; KM-unl; Cal-unl. 27.20 grams. Lustrous fields (only the flat, high points cleaned), particularly around the bold date and oMF and denomination 8, full but somewhat flat shield and cross (also flat in peripheries), no toning. The very clear date on this coin provides an important insight in that the last digit is 0/7 (with flat top), not 0/9 (despite what the NGC label says), and therefore a new (unlisted) overdate, supported by a clean assayer F as opposed to F/A. This is the first clear example we have seen, although more careful examination of other coins cataloged as 1610/09 might reveal other 0/7's. NGC #6284506-003. Pedigreed to the Kempen Treasure hoard (stated on label).
