Verb to not sell particular items?

[Shari]

I could have sworn there was a verb where if applied to the item you were holding it would make it unsellable. I just sold one of those blasted crystals from the Frontier Days shops to the gemshop. 20k Bravery crystal...POOF.

Any help would be great, thanks!
