Coin Operator

Coin Operator is a special perk in the Fallout: New Vegas add-on Dead Money.

It is received from Christine as part of her dialogue: several Perception and Intelligence checks are necessary, along with polite responses. To get the proper line of dialogue you need to ask her if she knows what the machines around the Villa are for. A dialogue option to acquire this perk has a Perception check of 6 followed by an Intelligence check of 6.

Effects
The result is Christine teaching the Courier a workbench recipe to make "slugs" that Sierra Madre Vending Machines can use: 1 fission battery plus 2 scrap metal = 50 Sierra Madre chips.
