This item is recieving higher offers than the current 21-24 key range. -- only 6 trades on OP, some of them looking for other items.

Sellers:

http://www.tf2outpost.com/trade/9721312 -- offer of 25 keys (he's collecting them), his B/O is about a bud..

http://www.tf2outpost.com/trade/8723704 -- a month old, recently bumped, apparently had a C/O of 1.3 buds

http://www.tf2outpost.com/trade/9068087 -- had offers of a bud around a few weeks ago, month old trade, b/o is a bud.. weird how he hasn't accepted any offers yet. Recieved a 'maybe' offer of 24 keys, obviously hasn't accepted.

http://www.tf2outpost.com/trade/9587737 -- offer of a planets connoisseur cap, (24-30 keys), his b/o is like a bud + 8 keys for the guadalajara

http://www.tf2outpost.com/trade/9891668 -- 1 bookmark, selling for 24 keys, no offers yet

From my gatherings, I reckon the current price is too low and it is recieving higher offers (the 21 key low end currently is kinda unnecessary) and many B/Os of a bud (although b/os do not dictate market value, they are useful)

:C no hate pls, my first unusual suggestion, suggested this because someone offered this on my buds and I looked in his trades to find higher offers than the current value.
