2011 United States Army Commemorative proof

Evidence of clashed dies is not common, but on proof dies, it is extremely rare. In this particular case a 2011 proof Army Commemorative obverse shows visual indication that the obverse die clashed upon a reverse die. However the reverse die does not show any indication of reciprocal clash marks suggesting that a Mint employee probably switched out the reverse die, and for an unknown time, left in the obverse die to strike blanks into coins.

The first illustration shows an approximation overlay diagram showing the position in which the dies appear to have struck one another.

Next, in the lowest point between the two helmets, we see clash marks of the shield, the outline of eagle’s neck, ribbon and the negative space between them and the eagle’s feathered wing

A close-up of the overlay diagram showing the areas in question is seen below
