How to determine a Doubled Die

I'm trying to learn as much as possible in regards doubling. My quest is to learn about more than just the obvious doubling I e. 1955. I find facinating how an attributor can look at a coin under a scope and can tell that it has working hub doubling due of the variance in thickness either on letters or the date and which direction the doubling is taking place with any noticeable notching or splits simply thickness alone. Can anyone answer how an attributor is able to judge that. Thank you.

    How do they know? Experience from looking at lots of coins plus a solid understanding of the die making process.

    The following sites list doubled dies. Spend some time looking at the pics. Wexler's doubled die site also explains the die making process and has a section on worthless doubling (mechanical doubling, due deterioration, etc).

    @1941ljt....Welcome aboard.... Take the advice above, you will learn a lot. Then look at as many examples as you can find - pictures are good, but in hand is better - a visit to a coin show or coin shop would allow you to see a lot of coins with DD's or other doubling. Good luck, Cheers, RickO

    The info at the above link (John Wexler's site) will tell you everything you need to learn!


    Short version: If you are lucky, the coin will have "strong split serifs."

  • Thank you for advice. I really appreciate it.
