I have a good idea of the bottom end of the q9 prices, but am not entirely sure what the top end is for any of them. However the q8/10 items I am surely lost on. I organized things by req to make it easier to sort through.
Req 8
Only one max mod, but has that extra clean gold value
Super rare skin with double mods at q8
Single mod, but max q8
Req 9
1
2 (note the hsr is 1 off for this one)
3
4 (Clean gold value!)
5 (same as above but without the cool gold value)
6
7
8
9 (I have to admit, I actually do like seeing all of those rolling 9s there)
10
Req 10
1
2
3
4
