I am the other seller at 52 and as I said in classifieds I was quickselling it because I needed the pure but I actually have received some offers for around 63 keys and even more in unusuals:

Here are some of the offers, dont know how much the photos are going to last but I hope everyone can see them and if not please tell me what program can I use to take screenshots:

Burning Flames Metal Slug(60)+Strange Prof killstreak Loch-n-Load(around 2 keys) http://prntscr.com/eta7f9 http://prntscr.com/eta8ag

Spectral Swirl Taunt: Flippin' Awesome ( 65-75 keys) http://prntscr.com/eta8us

Burning Flames Ol' Snaggletooth(65-75 keys) http://prntscr.com/eta9f8

Power Surge Killer's Kabuto: unpriced yet but 1 seller for 55 keys and the other for 60 http://prntscr.com/etaah8 http://prntscr.com/etaap9

So I dont think a drop in price is actually necessary, also I though u could not make a suggestion based only in 1 sell and I no longer need to quicksell it for pure anymore so the most likely is that im going to modify my listing
