    They are punched into the die by hand, but it still becomes part of the die.

    Mechanical Doubling, but still looks neat.

    Machine doubling happens during the strike.

    It's definitely MDD. The mintmark is applied AFTER to die is made.

    If it too has doubling, can't be a true doubled die.

    Great example of machine/mechanical doubling. No numismatic premium, but worth keeping in the 'education album'.... Cheers, RickO

    Interesting to see what new collectors think. Imagine people sitting around a table putting the mint mark S on 890,000,000 coins that year.
    The reason it is called "shelf" doubling is that it looks like a shelf coming off the letters. Think of it as you think of a reef in an ocean. The land is above water the reef below, and it's a reef shelf that extends out into the ocean for a ways before it drops into the abyss. Looks just like it doesn't it?
