1-2k $ if you are very trusted. If people don't know you I think the max people will offer is 500-800$ ( but imo that would be a waste to sell for that price)
Sold off a max main a couple day ago with 2.1k tot/ 5 elite diaries completed. just about as much untradeables+pets as you have displayed. I reduced the price from 1b to 750M and it insta bought the same day and the dude went first with me. So i'd say you could get just about a 1B-1.3B for it imho with 100+ more total levels/completed diary cape then what I sold my acc for. Unless you plan on going full trihard and waiting a month or 2 before someone makes an effort to buy it off you. Good luck if you are trying to sell it!
