1904 Liberty Head Double Eagle. MS-63 PL (NGC). Mirrored fields surround lightly frosted devices of this attractive, Select Uncirculated 1904 twenty. A high-mintage double eagle (more than 6 million pieces struck), the 1904 is the most common date of the series, yet it is scarce with fully prooflike fields. Only a few light abrasions can be seen on the mirrored fields, and the strike is razor-sharp.
