When valuing paper money (and coins for that matter) condition plays a huge role. I am not an expert myself, however, posting some pictures of your bills would help out the experts.
Also, I believe you are referring to the 1969E dollar bill, you are talking about a series 1969 $1 with a giant letter E on the left side of the bill. The E indicates it was printed in Richmond (

The were dollar bills produced that read "series 1969 A", as well as B, C, and D. So when the other poster commented that there was no series E that is what he was referring to.

I do not own these images
Also, if the bills were part of a low production run, that would could add value to them. One Great website that helps determine if a dollar bill is low printing is
http://www.uspapermoney.info/serials/ (click on $1 in the summary row at the top of the page to see the old years). If your bills are series 1969 printed in Richmond, they printed 250,560,000. I am not sure what the cutoff for a "low production run" is, but considering it is the third highest for that year, I do not think it qualifies.
Hope all of this helps!
