Why do you think its special? I want to share this web page with you. http://www.onedollarbill.org/decoding.html
I have found bills with the high letter suffix. (W, X etc.) No extra value. Unless it is old, rare, crisp, low run, etc. Your note appears to be a circulated 2009. Why would it be worth more than a $1?
When the banks and money markets were paying interest that may have been true. I am not so sure anymore. Save a hundred dollar bill and in time it is worth less and less with no interest earned.
Also... Even if it had some kind of interest for a collector the condition of your note is not that good. Collectors want crisp clean bills. No folds or stains.
