2007-D

Denver struck 3,920,000 Sacagawea dollars for circulation in 2007, an output that put the year-end pair (Philadelphia plus Denver) just under eight million pieces and locked it inside the 2002 through 2008 plateau the program settled into after the 2000-2001 launch surge collapsed. 2007 carries an extra historical wrinkle. In September of that year, Congress passed the Native American $1 Coin Act of 2007 (Public Law 110-82), which mandated annually rotating Native American reverses beginning in 2009. The 2007-D was therefore struck during the legislative cycle that ended the Soaring Eagle reverse, but the design change itself did not take effect until two years later. Glenna Goodacre's Sacagawea obverse and Thomas D. Rogers Sr.'s soaring eagle reverse held the coin's appearance unchanged through 2008, on the smooth edge the 2009 redesign would replace once date and "E PLURIBUS UNUM" moved to the rim.

For the 2007-D specifically, the live authentication issue is not counterfeiting but Satin Finish confusion. Denver also produced a 2007-D Satin Finish dollar for the U.S. Mint Uncirculated Mint Set at 895,628 pieces, and the two coins share the same date and mintmark. The circulation strike shows ordinary cartwheel luster across both fields and standard bag marks from high-speed press work; the Satin issue reads matte across the field with crisp device edges. If the example reads matte, it is the Satin coin and belongs in the separate Mint Set entry. Strike on the standard 2007-D is generally clean for the alloy, with full hair detail and crisp eagle feathers from short die runs. Spotting (dark dots that develop on improperly stored brass-clad pieces) is the secondary concern on long-held rolls.

The 2007-D is a Regular classification piece. Sacagawea specialists working through the 2000 to 2008 Soaring Eagle dates treat it as ordinary supply for grade-set purposes through MS66, with MS67 thinning out and MS68 becoming a genuine condition target. The Professional Coin Grading Service and Numismatic Guaranty Company population reports show the 2007-D in line with adjacent Denver years rather than standing apart. Original mint-sealed rolls remain the most efficient acquisition path for raw collectors.
