How much is my runescape character worth if id decide to sell?

my runescape character has 99 atk 99 str 99 def 99 hp 90+ range 80+ magic , over 80 pray ,70 + summon 80+ mining That is maxed melee, close to maxed range. I havent done alot of quest but my combat is very good in my opinion and you can already or will soon be soloing half the rooms in god wars dungeon. so you have that way for substantial cash, easy of doing barrows at high lvls, and also ability to mine rune with a potion. account has a dragon fire shield 20 mil , robin hood hat 3 mil , skill capes, and also a fire cape which is award for defeating jad. only cape to give 6+_ str. and other smaller items ranging up to a mil.
