I think this cent might be Coppercoins.com die #18,here's the link tell me what you think. http://coppercoins.com/lincoln/diestate.php?date=1962&die_id=1962p1do018&die_state=mds
Does not look like die 18 as I am not seeing extra thickness or separation lines on the date. I'm not immediately seeing anything that would indicate a doubled die. There are quite a few doubled dies listed for this date, though...so it doesn't hurt to check. Keep up the hunt!
