Rolled-in scrap, steel sinuous wire

A 2000-P Maryland quarter with a long piece of steel wire embedded in the obverse. The wire runs beneath the outer clad layer as it skirts the word UNITED. The tip of the wire reemerges for a short distance before terminating (red arrow).  The clad layer has split along the path of the wire, exposing the copper core. The copper core is also exposed along and just inside the rim, possibly indicating the presence of a second wire that lay just outside the area sliced through by the blanking die.
