Watch List notes:

Anguilla, 1 "Liberty" dollar, July 11, 1967, countermark on a Mexico City, Mexico, 5 pesos, 1948, Cuauhtemoc, NGC MS 63 ("top pop"). KM-X2. 30.00 grams. Broad flan with nearly all the host-coin details still discernible, muted luster and faint toning, the Anguilla lettering dark and bold as usual, highest grade for this host date and second highest grade for the whole series. The story behind this incuse countermarking is that the editor of the San Francisco Chronicle at the time, a coin collector named Scott Newhall, wanted to raise funds to support Anguilla (which at the time was under the control of neighboring St. Kitts) in a bid to return to the British Commonwealth by selling some 11,600 coins so countermarked, but in the end no more than 3000 coins were released and the maker was stuck with the rest.
