Resuggesting with several tips (Using old bud prices, rounding numbers, one of the current owner's value on the Veil, etc) :D

4 month old price.

Only 2 clean recent sales between 4 months ago (The previous suggestion date) and now. One was one week ago, one was 3 months ago.

Sale #1: 18.2 buds (1 week ago)

Clean Ghosts Yellow Belt + 11 buds + 32 keys

http://backpack.tf/profiles/76561198071930142?time=1403506800 --> http://backpack.tf/profiles/76561198071930142?time=1403593200

6 buds x 0.9 = 5.4

11 buds = 11

32 keys = 32/17.5 = 1.83

Total = 18.2 buds --> Rounding down to 18

Sale #2: 14.6 buds (3 months ago)

Yes, this is somewhat old but is the only other recent sale between 4 months ago (The last suggestion date) and now.

14 buds + 12 keys

http://backpack.tf/profiles/76561198083262940?time=1397199600 --> http://backpack.tf/profiles/76561198083262940?time=1397458800

14 buds = 14

12 keys = 12/19.5 (Key price at the time) = 0.62

Total = 14.6 --> Rounding to 15

EXPLANATION FOR USING THE SECOND SALE

Yes, it is relatively old, but one of the current clean owners is valuing his Veil at 15-16.

His value on the Veil matches with the older sale, thus it would probably be better for me to keep it.
