Watch List notes:

Potosi, Bolivia, cob 1 real Royal (galano), 1733 E, retrograde E to right of cross, extremely rare, NGC XF details / holed (not listed in census). Janson-46.6.2; S-P46; KM-unl; Cal-unl. 3.43 grams. Typically thick, round, even, but small-diameter flan with perfectly centered cross showing a clearly retrograde assayer E to right, the pillars side slightly off-center but with bold E in proper rotation at top-right, with lovely old toning but inevitable hole near top of cross / top of right pillar. It is quite possible this 1733 E is unique, as the erroneous Janson citation with assayer E makes reference to and shows a photo of the "Americas" collection example of 1733 YA (also unique). NGC #5902427-012. Pedigreed to the Heritage auction of January 2008 (lot #50309).
