Driver Nephi's head

Driver Nephi's head is a miscellaneous item in Fallout: New Vegas.

Characteristics
After killing Driver Nephi, you can search his corpse and take his head which you can deliver to Major Dhatri for a reward as part of the quest Three-Card Bounty. If you shatter his head when killing him, you will instead be able to take Driver Nephi's mangled head, which serves the same function in the quest, but gets you fewer caps in your reward.

If you do not search the body and take the head immediately after killing him, his corpse will remain where he died to be looted at any point later in the game.
