History, Information, and Value of 1858-O Gold Liberty Double Eagle
Value of 1858-O $20 Gold Coin
The 1858-O $20 double eagle is a great rarity, with fewer than 150 coins believed to exist in all grades. When one can be found, high grade coins usually show prooflike surface, especially on the reverse, a quality typical of double eagles minted in New Orleans. The strike is typically poor, with weakness across most of Libertys hair elements. Scarce in all conditions, the majority of survivors are confined to Very Fine and Extremely Fine grades, with AU examples proving to be very rare. Just five or six Mint State pieces are known, the numerically finest of which is an NGC-graded MS-63, though Doug Winter believes the Bass specimen, currently certified as MS-62 (PCGS), is a finer coin. Certified grades are often inconsistent, making comparisons difficult.
