1900-O Barber Quarter. Type I/II. MS-67 (PCGS). Here is an incredible Superb Gem that really needs to be seen to be fully appreciated. Both sides exhibit vivid target toning in multicolored iridescence that includes brick red, antique gold, powder blue, silver-olive and medium rose. Small circular areas in the centers remain virtually brilliant. It is intensely lustrous, has a sharply executed strike, and offers essentially pristine surfaces. The Pogue 1900-O Barber quarter is among the finest known, and it would do justice to an advanced collection of Barber and/or New Orleans Mint coinage. Beautiful!The Type I/II hub combination is not among those listed for the 1900-O by Steve Hustad (per Q. David Bowers, <em>A Guide Book of Barber Silver Coins</em>, 2019 edition). He reports only Type II/II and Type II/III for this New Orleans Mint issue although with no center cartilage in Libertys ear, the present example was clearly struck from an obverse die prepared using the Type I hub.
