    I was wondering if anyone else found this effect on their SAC dollar from the Philadelphia set.

    It looks like a nice bit of machine doubling. I haevn't gotten my sets yet so I don't know. Heck, I might not even buy a set this year.

    i agrree with the smarter folks, but from my point of view... machine doubling or not... its got a cool effect going! the doubling is so uniform across the letters. very neat!

    Thanks for the responses. I could tell it wasn't a double die and figured it was machine doubling. I agree with Daggarjon that I thought it looked interesting because the doubling was so uniform across the lettering. I have a couple questions:

    Is machine doubling and shelf doubling the same thing? What happens in the process that causes it?

    Would a uniform doubling like this increase or decrease the value of the mint set?

    from what i have seen, any machine doubling is most always considered damage, and thus worth less then face value :(

    this type of doublin happens when an element shifts while in the pressing motion. someone else might be able to provide better explanation lol
