1906-D Liberty Head Double Eagle. MS-63 (NGC). This sharp and inviting example is awash in a lovely blend of rose-gold patina and bright mint luster. Liberty Head double eagles were struck at the Denver Mint in the years 1906 and 1907 only. 620,250 examples ($12,405,000 face value) were coined at the facility during its first year of operation. The Mint State population is estimated at the mid four-figure level, which means that many collectors will have the opportunity to acquire an attractive example of this historic issue.
