What does a CTU go for these days and is it worth it?

Hey all,
First post here. I found this site looking for places that buy bulk amounts of copper cents. Currently I have 4 CTU's and while I have dumped lots of copper before I want to avoid doing it now. Second part, if I finally am able to get rid of all my copper, is it worth it to keep going?
