there it none. Adsense does not work that way. You could have a medical site and get $20 per click and only be able to get 1 click a week because the competition is tough or you could be getting 7cents a click with 2000clicks per day.
That is what you need to figure out ;-) The highest paying niches are highly competitive and very difficult to rank well for. You need to find an untapped niche, not an easy task. That is what keyword research is for
Loans, Credit Card, Insurance etc would be niches I'd look into although adsense isn't my thing so I'd create my own contexual ads for affiliate programs.
I knew some but I won't tell you There are alot of untapped obscured niche, just look around and do some research. Your everyday-thing(ex. a certain type of soap, or some sort of rice) can be a good niche no one compete for.
