The one on scrap is clean so I see no problems with this.

So Scrapprehensive only actually got this on the 29th: http://backpack.tf/profiles/76561198135388328#!/compare/1495929600/1496016000

Item histories/the "last exchanged" button don't show this information accurately, they only show when the previous owner was last seen with it. For backpacks not often scanned this is misleading. Item ID# is the most accurate indicator, but checking Scrappehensive's backpack works too (although far more annoying). Since it's in there though we'll need to keep an eye on it either way, and this will be fine if it remains unsold - posting this mostly for informational purposes.
