I just sold my Sulphurous Trilby for 3 buds + 10 keys + White Vintage Tossle Cap, and I added my Orange Level 99 Bolt Boy and Orange Fast Learner (Basically 3.6 buds). Screenshot: http://imgur.com/hNFJ5mR, and my old trade: http://www.tf2outpost.com/trade/12198010

Other highlights include a Ghosts Spartan (offered by Pilltacular to me), which had an offer of 3 pure on his trade. I was also offered a Vivid Trilby + 1 bud, and an Eerie O. Fire Fedora + 1 bud (all personal offers through Steam Chat, you'll have to take my word for it at the moment).

I bought the hat for a G. Energy Crown, and he added about 0.4 buds. http://imgur.com/H2gkHNu (My previous trade: http://www.tf2outpost.com/trade/12050861)

Note that the hat is level 1, and he said he really liked G. Energy, and the hat was 1 of 1 on Outpost at that time. G. Energy Crown bp.tf range = 3.3-3.6. I'm going to wave off the "overpay" because the hat is Level 1, and people will *generally* pay a bit more for a nice level anyway. (Even if not, I don't think the price change will be significant for this hat). 3.3-3.6 minus 0.3-0.4 gives a range of about 3-3.3 for this hat, which is what I bought it for. Average would be about 3.2, rounding up.

Therefore, I feel a range of 3.2-3.6 seems about right. This matches basically perfectly with the Phos Trilby range (2.9-3.9, I just bumped up bottom side by 0.3 and shaved off top side by 0.3, still same average price), which makes sense because Phos and Sulph are basically equal.

Any suggestions? Only two sales that I know of so far, both from me. Comments and constructive criticism is appreciated, I believe this is only my fourth or so Unusual suggestion.
