Seeing as 1-40 is one of the hardest levels to obtain doing lamps and such also has a 99. Anywhere from 25-30m 07 would prob be best fit. A lot of people don't have the patience to do it and 40 you can wear decent armor. Lvl 60+ at 10hp a lot more value is say double if not triple in price because u can wear dragon and this is fashionscape so a lot of people would want it.
This is the kind of account that the value really depends on if you find a dude that is after an account like this, because if you don't I dont see it going for more than 10-15M
