Not good. 1 cent a click depends on site topic but you should get some clicks worth more than 1 cent.
That's very very bad EPC. Even smart priced accounts get more than that. May be you've got some invalid clicks
I think you're either being smartpriced, or being hit by MFAs. Use something to track your clicks and use adsblacklist.com to get rid of the MFAs.
Definitely, I'd say you're only getting credit for a few dozen of those clicks. Is 500 clicks for one day? Or an overall click balance? How long did it take to get that many clicks? What are your domains?
