Kentucky State Fund Dollar from the 1915 Panama-Pacific International Exposition in San Francisco. "King" of the 20th Century So Called Dollars, unlisted in the first edition, with perhaps less than 50 specimens known in all grades, mostly damaged. This is Choice Uncirculated NGC MS-62BN, the only certified specimen in existence as of early 2019. Attractive light brown surfaces with traces of original Red and no significant marks. The only limitation in grade is likely the tiny Obverse spot - or NGC's possible nervousness in assigning a grade to something which has never been seen before. In discussions with other knowledgeable dealers in the series, perhaps one other known, which has not been presented for grading. The total NGC pop is FIVE including this one, none other better than AU-58, and that number is unlikely to be increased anytime soon. Almost all known are damaged and holed, and just finding one that will grade is almost impossible. For your consideration: HK-149, another rarity, has a similar population and grade distribution, with four total NGC/PCGS (2-58, 1-61, 1-64PL), and an AU-58 is currently being offered on ebay at an eye-watering price (a bit silly perhaps, but it gives you pause in considering fundamental value). The famous HK-296 Wells Fargo medal has well over 120 at NGC/PCGS in Unc grades plus many others known in the original case left to grade - and they bring $1200 to $2000 all day long! I should also point out that the infamous 1909-S VDB Cent has a PCGS Pop of 1,300+ coins in MS-65RED and better; compare that to many of the rarest SCD. This remains one of the most undervalued areas in American Numismatics. As for this example, I really don't care if it sells immediately so the listed price, while it may seem "stupid" can be seen in the light that once sold, is irreplaceable unless lightning strikes again!
