1907-D

Denver's coining presses fell silent on the Coronet design after this issue, making the 842,250-piece delivery the final chapter of a Mile-High mint relationship that had only opened the previous year. Together with the 1906-D and its 620,000-piece run, the 1907-D forms a closed two-coin Denver subset within the Liberty Head Double Eagle series; collectors assembling a complete D-mint Coronet $20 set need only these two dates, and once secured, the run is done. By the time these eagles left the press, Augustus Saint-Gaudens' new high-relief design was already preparing to take over Philadelphia's coining floor, and Denver would not strike another double eagle until it joined the Saint-Gaudens program in 1908.

Strike quality on this issue tends to favor the collector. Denver's dies produced sharply impressed devices on rich orange-gold planchets, and a small number of survivors display fields prooflike enough that NGC has even certified at least one specimen-grade example, a coin whose status remains a numismatic curiosity since no contemporary documentation supports any official proof or presentation strikes from the Denver facility in 1907. Most pieces grade in the AU-58 to MS-62 band, where they trade at moderate premiums over melt; choice mint-state examples through MS-64 are available with patience, while gem MS-65 coins thin considerably and anything finer ranks as genuinely scarce.

Population data underscores how the grading curve compresses near the top: PCGS and NGC together report only a handful of MS-66 pieces and just a sliver above that level, and the auction benchmark reflects this scarcity. A PCGS MS-67 example brought $74,750 at Stack's Bowers in March 2012, a price that has anchored the date's high-end market ever since. For most collectors, however, the 1907-D's appeal rests less on absolute rarity than on its closing-act significance, the coin that ended the Coronet $20 in the Rocky Mountains.
