2006-D

Denver struck 4,900,000 Sacagawea dollars for circulation in 2006, matching Philadelphia and ticking up from the 2,520,000 piece-per-mint floor of 2005. The lift was modest (the program had bottomed in 2005 and Mint set demand drove the small rebound) but the issue still belongs to the run of post-launch dates the U.S. Mint produced more out of statutory obligation than circulation need. Glenna Goodacre's portrait of Sacagawea carrying her infant son Jean Baptiste runs on the obverse; Thomas D. Rogers Sr.'s soaring eagle reverse stayed in service through the end of 2008. The edge is smooth, since the 2009 Native American redesign was what moved date and motto off the obverse and onto the edge.

Two distinct surfaces left Denver in 2006. The bag-quality circulation strike covered here came out of high-speed presses and shipped to Federal Reserve banks in standard rolls; the 2006-D Satin Finish, packaged exclusively in the U.S. Mint Uncirculated Mint Set, used burnished planchets and specially prepared dies for a matte sheen and is tracked under a separate slug. Authentication on the circulation strike is straightforward, since the ordinary cartwheel luster reads completely different from the Satin field. Strike on the regular issue is generally clean, with full hair detail on the obverse and crisp eagle plumage from fresh dies running short production. Watch for planchet streaking from inconsistent burnishing of the brass clad surface; not damage, but it caps grades at the high end and pulls otherwise-clean coins out of the MS67 register.

The 2006-D is a Regular classification piece that a date-and-mint set builder still treats as meaningful, since the 2002 through 2008 run is where the series gets genuinely scarce in absolute mintage terms. The condition target is MS67 with strong luster, where the Professional Coin Grading Service and Numismatic Guaranty Company populations are healthy enough to keep pricing reasonable but selective enough that picking carefully matters. Raw rolls from the original Federal Reserve wrap remain the most efficient acquisition path.
