15 is WAY too high for the DP glove. it has been unsold for 3 months and its currently priced at 12. I guess I can try to update it if its really needed, as well as the other sales Ive researched. Just posted this on the previous suggester:

Sale 1:

Sold for gifted bubbling bonk leadwear (~18)

http://backpack.tf/profiles/76561198074087200?time=1429426800 before

http://backpack.tf/profiles/76561198074087200?time=1429522826 after

0.9*18 = ~16*

Mini leadwear:

Sold for O.fire jeepcap (~18)

http://backpack.tf/profiles/76561198074087200?time=1429758566

*O.fire jeepcap is pretty far outdated, probably overstating this sale

Sale 2 + 3:

Sold for presidents roboglove (~12) || Sold for NnB bonnet (~11)

http://backpack.tf/profiles/76561198080040220?time=1428390000

http://backpack.tf/profiles/76561198080040220?time=1428895532

Histories:

Tsar: http://backpack.tf/item/3607003903

robo: http://backpack.tf/item/3625066663

bonnet: http://backpack.tf/item/469757799

Theyre both outdated and would require minis, but I assume the value will be roughly around this value

0.9*12 = ~11 || 0.9*11 = ~10

-> 10 keys

-> 11 keys

Sale 4:

Sold + bills (~2.3) for s.f minigun (~13) + 1 key

http://www.tf2outpost.com/trade/25483692 BO of 8

http://backpack.tf/profiles/76561198102692590?time=1427526000 before

http://backpack.tf/profiles/76561198102692590?time=1427617818 after

Capping at B/O of 8

-> 8 keys [probably low, might be an outlier; depends on the minis from sale 2 and 3]

Sale 5:

Sold for a bunch of taunts

http://www.tf2outpost.com/trade/25480003

http://backpack.tf/profiles/76561198035873922?time=1427218914 before

http://backpack.tf/profiles/76561198035873922?time=1427439600 after

Far too low, excluding

The other one with sales has probably been quickbought

Based on this Id say even 16 is too high.
