History, Information, and Value of 1866 Gold Liberty Double Eagle
Value of 1866 $20 Double Eagle
In general these coins are well struck with high grade survivors showing bold, if not sharp detail throughout the design. On the other hand, heavily abraded surfaces are the norm, and finding an 1866 double eagle with an overall smooth appearance is very challenging. Luster quality for this issue is average with most high grade examples displaying a somewhat grainy, lightly frosted texture. A few semi-prooflike examples with reflective fields are known to exist, but they are rare and seldom appear on the open market. In circulated grades through EF the 1866 is easy enough to obtain, such coins enjoying tremendous popularity with collectors given that this is the first Philadelphia Mint double eagle of the Type 2 Liberty Head design. AU examples are also relatively plentiful, but are difficult to locate with smooth, minimally marked surfaces. The 1866 is rare in Mint State and seldom encountered any finer than MS-62. Proofs of this date are exceedingly rare with fewer than 20 specimens known, perhaps no more than 15.
