1907 Extremely High Relief, Inverted Edge Letters Proof

Saint-Gaudens' Extremely High Relief double eagle patterns, struck in late 1906 and early 1907 before the series' commercial release, represent the first production strikes of his design on planchets. The full production across all Ultra High Relief variants is estimated at roughly 22 to 24 examples, making each variant among the rarest American gold coins. The Inverted Edge Letters variant, catalogued under Judd-1773 pattern dies, shows the E PLURIBUS UNUM edge inscription oriented upside down relative to the coin's obverse, a consequence of the edge collar's rotation during the striking sequence. The coin required up to nine blows of the medal press to bring the extraordinary relief up fully, a process incompatible with commercial production, and the Mint subsequently issued the reduced-relief HR business strike for ordinary commerce. The design itself is Saint-Gaudens' original unmodified work: striding Liberty obverse, eagle-and-sun reverse, MCMVII Roman numeral date, in the extremely high relief the sculptor intended before Barber's later modifications.

Attribution of a 1907 EHR Inverted Edge Letters requires edge examination in addition to the usual obverse and reverse review, since the diagnostic lies entirely in the orientation of the edge lettering. On a correctly struck example the letters read normally when the obverse is right-side up; on the Inverted Edge Letters variant they read inverted. PCGS and NGC both slab the variant with specific designation, and the third-party attribution is effectively required for any transaction at this price level. Strike quality is consistently excellent across the documented examples, as would be expected from medal-press production on selected planchets. Surface preservation is individually documented in pattern references and auction catalogs; each known example has a pedigree chain traceable through named collections back toward the original Mint releases. Counterfeit exposure, while theoretical at this rarity level, would be detected by any credentialed authenticator given the specific die and collar characteristics of genuine examples.

Market position for the 1907 EHR Inverted Edge Letters is that of a premier American numismatic rarity, classed with the 1933 Saint-Gaudens, the 1804 silver dollar, and the 1913 Liberty Head nickel among the U.S. coinage rarities that transcend conventional collector categories. Examples appear at public sale only in generational events, and pricing at those events consistently reaches the seven-figure range. Collector demand comes exclusively from top-tier American numismatic specialists and institutional holdings; private ownership is concentrated in a handful of prominent collections, and any appearance of an EHR Inverted Edge Letters at auction is itself a reportable numismatic event. Acquisition requires PCGS or NGC certification without exception, with pedigree documentation typically included as part of the transaction record.
