A circulated 2005-P Minnesota quarter is worth face value — 25 cents, and most uncirculated coins retail for under $7 ($10–$50 in MS67). The money is in the Extra Tree doubled-die reverse: the strongest variety (DDR-001, FS-801) shows a ghostly extra spruce beside the treeline right of the state outline. PCGS puts it around $40 in MS65 and $275 in MS67. More than four dozen lesser doubled-tree dies have been identified, and those minor versions bring smaller premiums — so identification matters before you pay up.
To check your coin, confirm the "P" mint mark on the obverse, just right of Washington's ponytail. Then examine the reverse with a loupe: on the doubled die, faint extra tree outlines appear immediately to the right of the fourth evergreen, near the "Land of 10,000 Lakes" banner. An "S" coin is a proof, and 90% silver 2005-S proofs also exist.
