With a mintage figure of just 5,500 coins, the 1857-O is the third scarcest No Motto eagle from the New Orleans Mint, trailing only the 1841-O and the 1859-O. According to Doug Winter's newly-released second edition of his book Gold Coins of the New Orleans Mint, 1839-1909, there are an estimated 70-80 pieces known including 14 to 17 in the various AU grades. The 1857-O is one of the few eagles from this mint that has never been certified by the major services in Uncirculated.
