1857-O $20 AU55 NGC. The 1857-O double eagle has long been in the shadows of the three O-mint issues that preceded it, most notably the 1854-O and 1856-O rarities. Of the 30,000 double eagles coined at the New Orleans facility in 1857, only a small percentage survives. Indeed, it is doubtful that more than 150 examples are currently known, just half of one percent of the original mintage. Uncirculated coins are essentially non-existent, so any example that approaches Mint State status takes on even greater importance. This specimen is in very choice about uncirculated condition and shows lovely wholesome surfaces, a nice even strike, overall a very pleasing New Orleans Gold rarity which will please the fussiest of collectors of Type I Double Eagles. $19,950.00 Coin Values shows $20,000.00, 5/2008.
