The Twenty Dollar Liberty Head Gold Double Eagle, designed by James B. Longacre, was minted from 1850 to 1907. This turn-of-the-century example was struck at the Philadelphia Mint in 1899 and is graded in Mint State 63 condition. Out of every 1899-P Liberty Head Double Eagle struck, less than 1%  have been graded in MS63 condition. With such a low MS63 population, this Liberty Head Gold Double Eagle is a true Condition Rarity.     Coins like this 1899-P Liberty Head Gold Double Eagle became increasingly rarer as a result of President Franklin D. Roosevelt signing Executive Order 6102 in 1933. This order sought to revive the American economy by recalling circulating American gold coins to be melted down.
