    Is there a known DD for this date/mm?

    If yes, does yours match exactly the photos of known exampies?

    If no, then why scrutinize It? ;)

    To be fair, if there is a known DD, there was a time when it wasn't known.

    I'd vote machine doubling. Study photos of true doubled dies and you'll learn to spot the difference.

    To be fair, if there is a known DD, there was a time when it wasn't known.

    1) I'm trying to make a point, that new collectors in particular should use existing knowkedge and resources to focus their efforts.

    2) if the coin was current (this year or last year, for example) then there may be a discovery to be made by anyone who is looking, but for the most part older DDs would already have been identified.

    P.S.: a sign of MD is flat and shelf-like doubling. ;)
