Referring to the evidence to back up this price drop, it was a discount for pure. The user sold his unusual at a discounted price to achieve pure with the mindset to cash out or to trade for other items. Looking at the statement "owned the hat for 2 years" I took the liberty to check all the unusuals history in his backpack. All of them havent been traded for in years so he most likely he discounted his hat of cards for pure. This hat does not deserve a price decrease since its relative effect, time warp, is freshly priced at 70 keys.

Be that as it may, backpack.tf aims to display what unusuals can sell for in pure. The best way to accomplish this is by using pure sales.

I do not see any indications that this should be considered a quicksale. "Quicksales" by our definition are only excluded if it is evident that someone was willing to take way lower than anyone else by listing and instantly selling at a low price. The user may have been cashing out, but he's had the listing for months. The fact that it took that long to sell at a discounted price supports the drop, if anything.

As such, this will be fine. If this indeed ends up being low, it can be updated again once it sells higher, but for the time being, this will suffice.
