It was pointed out to me that there was a possible die clash on my 1957 cent. I checked out
http://www.maddieclashes.com, and it seems like some of the type I counter clashes are very minor. On this cent, I see a strong line, the "N" from the CENT on the reverse of the coin, and a weak line protruding from just below the bowtie, even with the top of the date. Possibly part of an "E." A couple other questionable spots.
