2011-P Wampanoag Treaty 1621

Philadelphia matched Denver's output at 29,400,000 pieces in 2011, the third year of the annually rotating Native American reverse and the last full year of true circulation production for the Sacagawea program. The reverse, designed by Richard Masters and sculpted by Joseph Menna, shows the clasped hands of Wampanoag supreme sachem Ousamequin (Massasoit in colonial chronicles) and the English colonial leader sealing the verbal mutual-protection treaty negotiated at Plymouth in March 1621, with a ceremonial peace pipe between them. The agreement held roughly half a century before unraveling into King Philip's War in 1675. Glenna Goodacre's Sacagawea portrait stays on the obverse, with the date, P mintmark, and E PLURIBUS UNUM on the incused edge lettering introduced in 2009.

The 2011-P matters less for any one diagnostic and more for what came right after it. In December 2011 the Mint announced the same Not Intended For Circulation policy it had just applied to the Presidential Dollars, and Philadelphia's 2012 Trade Routes mintage dropped from 29.4 million to about 2.08 million, distributed only through Mint bags, rolls, and sets rather than Federal Reserve cash channels. That makes 2011-P the dividing line between the Sacagawea dollars a cashier could conceivably hand back as change and the post-2011 issues that effectively required a collector channel to acquire. The handshake reverse strikes up cleanly from fresh dies; fine modeling around the knuckles and pipe bowl softens as dies wear. No widely documented varieties have surfaced.

The 2011-P is a Regular classification piece. It trades at minimal premium over face in original-roll quantities, and the collecting interest is structural rather than scarcity-driven: this is the closing entry of the circulating Sacagawea era and the natural endpoint for a date-and-mintmark set built across the 2009 to 2011 fully struck Native American reverses. The Professional Coin Grading Service and Numismatic Guaranty Company populations run deep through MS66, with MS67 still affordable and MS68 the realistic high-grade ceiling. Original mint-sealed rolls and bags remain the most efficient acquisition path for raw collectors.
