Then dumped to stn for??

The STN sale sold (the 211 key mentioned above) for what looks like 242 on buyers side.

He bought a Sulphurous Fed-Fightin' Fedora for 135 keys and 37.66 ref

(ID 16970335068)

Which leaves the remaining 242 keys for the brotherhood (which all the histories match)

This also matches what STN currently has its sell price at (which was only because it was a day ago)

I would resuggest it at 242 - 300

Moose's information seems correct. But before you resuggest, I should reiterate that you should never round full pure sales. This suggestion should've been 211-300.

With Moose's revision however, it will be 242-300 instead.
