I'm not too up on errors but I found this roll hunting and saved it, can you tell if it is worth anything? .
If it is offset on both sides, it is a slightly off-center strike. If it appears offset on only 1 side, it would be a misaligned die error. http://www.cointalk.com/t223392/ Keep up the hunt!
And to answer your question, its worth at least 50 cents minimum. If its a misaligned die strike, it could be significantly more. Definitely a keeper if you're into this kind of thing. Typically, finding something that can be identified and validated as real or authentic, usually breeds interest in other things. For example, a misaligned die mint set would be a worthy goal. Especially if they are all from the same year and mint. PS: Please post a picture of the reverse.
