Thought so. I used to have lots of them with a similar traffic ratio, that's why I asked. Decided to get rid of them when I read a year ago that google was going to start banning adsense accounts from sites that had few content above the fold, so that might have been the reason why you were banned.
I did sold a couple of sites well, but the last batch I sold had an adsense revenue decrease the last couple of months, so they didn't sell at the price I could have sold them months before.
My advice is to try to have some earning history with the new ad platform and sell it on flippa. There's also an advertising platform that allows you to show ads inside your images, can't recall the name now, but it might be worth to try.
