Comments: CONECA does not list this variety. The Cherrypickers’ Guide to Rare Die Varieties suggests that a Denver Mint employee may have intentionally added the partial extra ear. Other severe rotations and offset hubbings have been recorded such as the major 2009-D District of Columbia doubled die reverse quarter and a number of Lincoln cent reverse doubled dies produced on the single squeeze hubbing presses.
