HK-411, Oregon State Fund Dollar, struck for the 1915 Panama-Pacific International Exposition in San Francisco.  Also catalogued as SH 18-24 in Jeff Shevlin's guide to West Coast Expositions.  Gem Uncirculated, certified NGC MS-65, pedigreed to the famous Ostheimer Collection.  As common as this piece generally is, even in lower BU grades, NOT so as a Gem due to how the surfaces were treated after striking.  Only 5 so certified by NGC after 30+ years of grading.  About as bright and flashy as one of these gets.  Shown at $350 in Shevlin's value guide; worth a premium for the Pedigree to one of the most famous SCD collections ever assembled, in my opinion..
