In my recent Pan suggestion one poster noted that this item could be seen on outpost selling for 9 keys. I promptly donned my detective's hat and made my very own magnifying glass and went to uncover the truth!

Aaaaaaaand then I found a relatively small market, 1.5 pages on outpost of recently-bumped trades, with some indeed selling for 9 keys. 10 keys is still evidently possible, though.

Classified listings at 9.5, 9.7 keys

-----------------------------

At first I considered 9.5-10 keys as a range, since there are only 2 9-key sellers. Its clear they aren't quick-sellers (if they are, they sure aren't selling quick), and the market is small enough that I felt two trades was...somewhat significant. I think the price could use a drop regardless, but if enough people feel 9.5-10 is a better range I can re-suggest.
