What type of contact mark is this, please? I've seen it before and, of all places, on a
different doubled die on Wexler's site, the picture of the 2015-P 25¢ NE WDDR-033 found here:
http://doubleddie.com/1467540.html(I'm sure they're not doubled die issues -- just a coincidence that I've seen this only on 2015-P doubled dies.)
Thanks in advance. :)
