Current trades:

-up for quite a few months, b/o of 10 buds, but it's not like he didn't receive good offers, just only wants pure

-recent notable offers:

stormy 13th tyrants=8.9

138 keys=8.6 then

duped ghosts tyrants+ghosts toque (both outdated)+45 keys=?

surge bomber+sweets=8.5+

kaw cm (7.5 before overpay)+miami hotrod (3-4 outdated)=9.9

-----

-some proof for hotrod:

http://www.tf2outpost.com/trade/16869198

-b/o of 4 buds

-seems to have sold for steaming exe: http://www.tf2outpost.com/trade/16352385

-seems to have sold for smoking antlers (unpriced): http://www.tf2outpost.com/trade/15588877

-using outdated steaming price this is ~3.3 buds

so probably a bit lower seeing b/os of 4 but range still fairly accurate

-----

secret mountain cap (year old price, looks lower)+63 keys=supposedly ~11 but more realistically ~9

-----

-proof for secret mountain cap (original price 8.4-9.4 with b/os at 8)

http://www.tf2outpost.com/trade/17153247

-wanted 6.5 buds (had other trades)

-cap+69 keys bought clean scorching phantom: http://www.tf2outpost.com/trade/17131728

-~6 buds

http://www.tf2outpost.com/trade/16900620

-bought anti-freeze salty (b/o of 7 buds)=roughly 6-7 looking at the high tiers

http://www.tf2outpost.com/trade/16751468

-bought disco madden (b/o of 7 buds)

so I would say roughly 6-7, at least not 8.4-9.4

-----

http://www.tf2outpost.com/trade/17114523

-b/o of 10 buds

-notable offers:

searing modest (outdated)+aces tin topi+blizz rebel=8.7

terror jefe (slightly outdated)=8.9 fitting in my range but honestly looks like lower

aces gibus=10.8, outlier and gibus looks like could be lower anyway

blizz exe (10 month old price)+73 keys=9.4

c9 cannon+terror raincatcher (unpriced)=looks like outlier

Sales: 7.4, 8.6, 8.7, 9.1, 10, 13

Low end is simple: notable offers starting from 8.5 onwards. 10 is high end due to a sale and rarer offers above 9 which is expected when looking at the high end. But obviously 10 is the max, most b/os are there. Overpay and original prices used.
