The circulation strike companion for the D. Brent Pogue Proof example.This is the finest known 1820 Browning-1 quarter in circulation strike format. A breathtaking gem, replete with the most stunning sort of satiny luster. Befitting a gem quality coin with a provenance over a century old, the rich toning breathes originality. The opalescent silver gray obverse is bordered in luxuriant tones of gold and attractive blue-green, while the reverse is more defined by its golden shades, decorated with glimpses of pastel blue and spring green. The fields are essentially pristine, with no significant contact marks, just a single microscopic hairline from beneath E on the reverse ribbon that crosses the open field under PLURI and hugs close to the top of the eagles beak. A more hidden hairline crosses beneath Libertys eye. When finding flaws amounts to seeking out individual hairlines, some idea of the surface and aesthetic quality of this piece can be inferred. The strike is without drawback anywhere from rim to centers, and the die state is crisp and early. Described in the 1997 Eliasberg catalog as no doubt the finest known, this coin is one of three Mint State examples recognized in the Rea-Koenings-Haroutunian census, ranked higher than an NGC MS-64 last sold in 2009 and an MS-60 from Auction 79 that may be a duplicate for one of the AU-58s on that roster. The Browning-1 is the second rarest die marriage of the year, narrowly edged out by the Browning-5 (the finest known specimen of which is lot 1065 in the present catalog of the D. Brent Pogue Collection). PCGS has assigned the MS-66 grade to a Large 0 variety of the 1820 quarter dollar on just four occasions; at least two of those represent coins in the D. Brent Pogue Collection.
