    What do you think about this 1996 quarter?
    What caused the doubling on the motto and the MM?

    I would say strike/machine doubling

    Here are 2 pics the first one has strike/machine doubling and the second has hub doubling.

    Correction, the first pic i think would be Die Deterioration Doubling.

    The ghostly doubling on your quarter is from overpolishing. Picture a buffing wheel polishing away at the surface of the die. If it is applied with a bit too much enrgy, it will wear away the crisp edges of the lettering and actually buff into the die along that edge creating a ghost image.

    Your coin is pretty neat! Good photos.

    I'm still learning about the different types of doubling. It seems that if the doubling is centered on the strike, it is strike doubling and if it's off-position it's hub doubling. Is that correct? If so, then Jody's coin looks like hub doubling to me.

    I'm so confused LOL

    I must be trippin cause the deeper i get into this error hobby the more confused i become, the pic i posted was the wrong one , it gets bad when you post a pic and describe it wrong??? WOW

    Here is the link where i got the pics and there is alot of info on collectible doubling and other worthless forms of doubling. So take a look and see what you can get from it.

    Okay. After looking at all the pictures and descriptions, I have a question. It seems that the collectable forms of doubling all have a full (not flattened) bottom image and top image. Is this true?

    That was what I thought caused it, too.
    It is evident, by the appearance of the fields, that the die is heavily eroded.

    Thanks, everyone that replied. :)

    It looks like die deterioration doubling to me. "Abrasion doubling" is largely a myth. The vast majority of claimed examples of abrasion doubling are simply die deterioration doubling.

    OK. Die deterioration doubling it is. I knew it was something like that. I assumed "abrasion doubling" because all the doubling seems to be going in one direction, like from a buffing wheel, instead of the all around randomness you'd expect from die deterioration.

    No doubt this is an intensely deteriorated die, with the dimpled surface and all. Amazing that it was still in use.
