Just updating an old price, it's 3 months old right now. Please leave feedback, this is only my 2nd price suggestion. Good or bad, all feedback is appreciated. I closed my last suggestion for this hat because the price suggestor changed the high range to 21, so the new price was 21 keys. For offers, I just put the highlights, but if there's only a couple I list them all.

Buyout: 1 bud

Offers: 17 keys + Purple Bills ( 25.5 keys, said he accepted it 3 weeks after guy offered, but guy sold Bills)

Vivid Plasma Stately Steel Toe (23-31 keys, but price is 4 months old)

16 keys + 2 Fast Learners (4 keys) + 16.77 ref (4.5 keys)

Nuts Buckaroo's hat + 6 keys (Same guy as first trade, accepted but guy sells hat)

Other trades: There is 1 other trade on Outpost. It is only 13 hours old and has no offers on Helm.

Conclusion: This hat is mostly getting offers on the high end or above the current price. The first trade owner is a little unlucky besides the Buckaroo, but the second is getting good offers. So, I think this hat should go up slightly.
