Items in Pokemon Black Version
If that link doesn't help then don't get mad it's my first link.
Any rare items, or atleast uncommon items, other than Relic whatevers are acceptable.
Most items in the game are "rare" in the sense that they can only be found once( such as TMs and special held items) uncommon items include things such as Nuggets and star dust, which can be sold. hope this helps :D
yes stuff like the relic vace,statue,copper,braclete
