    Hey everyone, Ive been collecting coins my whole life, yet I still cannot identify real doubling for the life of me. I can tell when its obvious machine doubling, but I can never %100 tell when its actual doubling. Ive been trying to find some physical examples to get a better understanding.
    So, I had several rolls of uncirculated 1968 s penny's I managed to score from a bank, and decided to look through them up close. I pulled out a couple that fit my idea of what a true double would look like, and will post them here. (I realize that they very well might not be real doubles). I was curious if yall see any real doubling in any of the pics? (multiple pics of 2 or 3 different coins)
    I try to look for the split serifs like it says on line, but I could be misinterpreting what it means by that?
    Anyway id greatly appreciate yalls opinion on whether or not any of these display real doubling, I'm trying to gauge if Im at least on the right track identifying them.
    Thanks in advance for any advice!

    Thank you! May I ask what you saw that made you realize it was for sure mechanical doubling?
    For example how can you tell the difference between the picture i'm about to upload of my coin vs the pics here of a real double die? http://www.varietyvista.com/01b LC Doubled Dies Vol 2/1968SDDO001.htm

    Also by "split serif" I alway thought they meant that the doubling would appear to put a "split" where the serifs of the letter/number would be like the 6 and 9 in this picture. Do you know what I'm misunderstanding? Thanks again for the help!

    Also.. The correct Numismatic terminology is Doubled Die.. Not double die. Big difference.

    Doubled Die varieties occur when the working die is made. The working die is struck twice by the master die (really a double squeeze). So that when there is a doubling on the working die (hence the name doubled die variety) that doubling gets transferred to every coin struck by that working die
