I sold a Serafi-senba board yesterday. Then again, they're only 1mil in shops, so it wasn't a huge loss lol.

Worst thing I ever sold to an NPC was a Creasaud+. I always pay extremely close attention to what I'm doing when I'm dealing with NPC shops, since some of my friends have had very bad experiences with accidental selling.

I sold a meteor cannon to an npc back when they first came out, that would have been like selling an Adahna Cannon to an npc now.

also sold a pair of 10/10 twin ruby bullets a week ago

Cresaud+ is supposed to be NPC'd...

Svaltus Sword when I was a lowbie... looking back I don't care much for that one.
A 28% Rabol Orachio; was NPCing a bunch I picked up for 100K during STD

Friend NPC's a love inferno [B] when they were 99mill. He got it with another friend and quit because he couldn't come up with the 49mill he would owe him from the 50/50 split. I laugh everytime i see him.

Back when the expansion first came out and you could finally unequip techs, I accidentally sold a Rabarta that I had just worked up to 40. I was so happy to have the tech finished that I unequipped it and equipped the next tech I was going to work up to 40. Then I went to the NPC to buy some photon charges and sell off extra crap. Rabarta was one of the things I sold and I didn't even notice it for a few days later when I was going to do Sleeping Warriors and wanted Rabarta for the Badira.
