Watch List notes:

Mexico City, Mexico, cob 8 reales, Philip V, assayer F, with "B" chopmark and "Sumenep" in Malay Arabic script countermark (Madura Island, Indonesia, 1 real batu, 1814) on cross side. S-M26; KM-47a. 26.66 grams. Very worn (Fair) with full oMF (very off-center shield) and some cross but the rest flat, toned on fields and inside the rectangular countermark and chopmark. It should be note for the sake of accuracy that countermarked coins like this technically should be attributed to the new country (in this case, Indonesia), although the larger interest today is unquestionably from collectors of cobs.
