Junders Plunkett's finger

Junders Plunkett's Finger is a unique item for those with the Lawbringer perk. After finding a Bounty Notice for Junders Plunkett on the body of a dead Regulator, Junders can be killed, and this item can be found on his corpse. When it is turned in to Sonora Cruz it is worth 1,000 Caps instead of the usual 10.

Note
Unlike regular fingers, Junders' finger acts like a quest item and cannot be dropped. In addition, it will often not vanish after turning it in, staying in your inventory forever. Since it has no weight, this is at best a minor inconvenience during PipBoy browsing. In fact, the script for killing Junders Plunkett is an automatic check, not involving the finger at all, likely meaning that it was intended to be removed from the game, but forgotten. Another theory for why Sonora doesn't remove this item from you inventory is, this might happen if the player never found the bounty note on the Dead Regulator.
