2011-D Wampanoag Treaty 1621

Denver's 29,400,000-piece run is the third entry in the annually rotating Native American reverse program and, as it turned out, the last Denver Sacagawea dollar struck for actual circulation. The reverse, designed by Richard Masters and sculpted by Joseph Menna, shows the clasped hands of Ousamequin (the Wampanoag supreme sachem better known to colonial chroniclers as Massasoit) and an English colonial leader, with a ceremonial peace pipe between them. The scene anchors the verbal mutual-protection treaty negotiated at Plymouth in March 1621 between the Wampanoag Confederacy and the Plymouth Colony, an agreement that held for roughly fifty years before unraveling into King Philip's War. Glenna Goodacre's Sacagawea portrait stays on the obverse, with date, D mintmark, and E PLURIBUS UNUM on the incused edge lettering introduced in 2009.

The most important point about the 2011-D is the timing: this is the last year of full Denver circulation production for the program. In December 2011 the Mint announced the same Not Intended For Circulation (NIFC) transition it had imposed on the Presidential Dollars, and from 2012 onward Denver's annual Sacagawea output dropped from tens of millions into the low single millions, distributed only through Mint bags and rolls rather than Federal Reserve channels. The handshake reverse strikes up cleanly when dies are fresh, but fine field shading inside the palms and around the pipe bowl flattens early in die life. Bag-handling marks on the open obverse cheek and forehead are the routine condition cap.

The 2011-D is a Regular classification piece. Its collecting weight comes from where it sits in the program's arc rather than from raw scarcity: it closes the bookshelf on the Sacagawea dollars that an ordinary cashier could conceivably hand back as change. The Professional Coin Grading Service and Numismatic Guaranty Company population reports show abundant MS66 supply, MS67 readily available at modest premium, and MS68 thinning out as the realistic high-grade ceiling. Original mint-sealed rolls and bags remain the most efficient path for raw collectors building a date set.
