Solds:

http://backpack.tf/profiles/76561198123977468?time=1433784135 (sold for a Misty Skull Copper's Hard Top + 3 keys) Couldn't find a mini for the hard top, but if we took the really old price it would be 44x0.9= 40 + 3 = 43 keys

Sold #2:

http://backpack.tf/profiles/76561198080018352?time=1433702458 (sold for a flaming latern little buddy) http://backpack.tf/item/1209052272

Mini buddy:

http://backpack.tf/profiles/76561198019680159?time=1432865627 (sold for a Searing Plasma Flipped Trilby ~ 30) ~ offered on

So this sale is 30 keys

Sale #3:

http://backpack.tf/profiles/76561198093399764?time=1432466502 (sold for a anti-freeze prancers ~ http://backpack.tf/vote/id/557732c6dea9e96b3d8b4572 ~ 65) x0.9= 59 keys

Markham Boy was offered a Pro Australium Eyelander (~45)

dyl4n lft heavy was offered a Vivid Plasma Federal Casemaker (40)

Both offers happened during the suggestion being open, but it shows 30 being an outlier more than 59.

As indicated in the comments, it looks like 30 is an outlier. Prancer also has a suggestion up, which after overpay would be 43 Keys.

Also, regarding on your first sold, you can't value the hard top by it's old price as it will be inaccurate in pricing by hats that are accurate.

Here's a mini on the Skull Copper:

Sold for Burning Sober (58 Keys) w/ 20 Keys ~38 Keys

http://backpack.tf/profiles/76561198026104036?time=1434783600

I doubt that it wasn't offered on the Burning Sober, but just in case, you should probably add the seller/buyer for additional information.

A range of 41-43 Keys would be better. ^^ ~ roller 2015
