Bought 3 of these at 14 keys each. Each of them sold for about 16 to 17 keys after only a couple of days. The price seems a bit too low and a bit out dated.

For my proof, I have this.

Also proving my point they can be sold for 16 super easily here.

This one was sold for 15 keys 1 day later as a "quicksell"

He said his C/o was TS bills + key + 6 keys in sweets, which is 16 keys aswell.

This guy got an offer of TS bills + 1 key + 6 keys in sweets, And he was also offered 15 keys + Tosslecap, I believe a tosslecap is worth 1 key.

I'll try and dig up some more information from my friend who sold his for 17 keys.

Furthering this proof.

Asked my friend to post his snapshot of him selling it for 17 keys.
