Watch List notes:

Mexico City, Mexico, pillar 8 reales, Philip V, 1733/2F, mintmark M.X, extremely rare, with chopmarks as from circulation in the Orient (unique). Gilboy-M-8-3b; CT-771; KM-103. 26.93 grams. This is a very interesting issue (and so rare that it is unlisted in the Freeman Craig treatise, also the first specimen we have offered), as it proves that the oddball "mintmark MX" die began in 1732, but that die was not used until this 1733 issue with 3/2. A diagnostic of this die, plainly visible on this coin, is a scratch on the die to the right of the right-hand pillar. In any case only two examples have crossed the auction block in recent years: The David Gray specimen (Ponterio, October 2014, for $16,000 hammer) and the Isaac Rudman specimen (Heritage, August 2016, for $28,000 hammer). What is unique about the present piece is that the pillars side is graced with three large chopmarks and one small chop, nicely toned XF with encrustation in places at rims, tiny square holes at top and bottom. ($6000-9000)
