This is a 1999 Pennsylvania quarter which is a deep obverse die cap. The coin has a moderate but obvious cap wall surrounding the reverse design, and on the obverse side is a full brockage of the reverse design. State quarter die caps are much nicer when the show the state side, and are more collectible as well. PCGS MS-66 with blazing white luster and no problems. A beautiful, dramatic, and very scarce die cap state quarter.
