    I will go out and pillage and plunder like the rest of the rioters if this turns out to be machine doubling. That doesn't happen on proof coins too does it????

    Really unnecessary comment. :facepalm:
    What you said is sad.
    It's a very sensitive issue these days and any time.

    Oldhoopster It seemed like a good idea at the time.

    The letters are thinner. True doubled dies CANNOT have this characteristic.

    You may want to read up about the minting and die making process at www.doubleddie.com. Once you have a basic understanding of the process, the frustration level should go down.

    If you go back through your old posts, I believe people have given you links to study the die making process. Spend some time looking at them. It will help

    I think proof coin are prone to machine doubling because they are struck twice and business strike coins just once.

    In fact, Yes it does -"Very Rarely" due to the smaller number of mintages and much more stringent QA process.

    Is the coin still in the holder from the mint? If so, how much distortion are you getting in the photos?

    Sorry, didn't mean to offend, I only meant it as to say "I protest!" I guess I'm desensitized, I've been around riots a few times before.

    I have, but not many give much detail on proof coins and precisely. There doesn't appear to be great interest in errors on proof coins outside things like missing mint marks.

    After carefully looking at this coin and the doubling, while it appears to have the same shelf like details of machine doubling, I'm almost certain it is not. From the looks of this coin, the "machine" doubling, is in fact coming from underneath the devices. Meaning, that machine doubling isn't machine at all, it's man made. The coins being stuck twice provide for a final opportunity for misaligned strikes in the minting process.

    Here's a few more pics. You can see lines from yet a 3rd "doubling" strike nearly completely erased but underneath the other two images. Also, the whole coin every detail, no matter how small is doubled, right down to the creases in the jacket and curves in his ear.

    Ok.. Cool man.
    I also say your coin is Mechanical Doubling.

    I like to call it MDD (Machine Damage Doubling).

    Yeah, after looking at it some more, that 3rd strike isn't a 3rd. The 2nd strike was so strong that it obliterated the various sections of the devices and slammed its way past them right onto the field. That's why all the detail is all there and all the doubling is all flat as a pancake.
