Watch List notes:

Popayan, Colombia, 1/4 decimo, 1867, normal stars, very rare, NGC VF details / environmental damage, finest and only example in NGC census. Restrepo-248.9; KM-143.2. Crude strike as usual (no rims), with a few light patches of toning over surface corrosion and marks, so rare that Restrepo says "two known," the numbers and letters somewhat odd (possibly a contemporary counterfeit) and rather different from a superior specimen in Eldorado (PCGS AU55, hammered at $1100). NGC #6442573-015. Pedigreed to the Bernal Collection (stated on label).
($200-300)
