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
The finger will often not vanish after turning it in, staying in your inventory forever. Though as it has no weight, this has little, if any, impact. In fact, the script for killing Junders Plunkett is an automatic check, not involving the finger at all, likely being that it was intended to be removed from the game, but forgotten.
