Counterfeit bottle cap

 is a miscellaneous item in Fallout: New Vegas.

Characteristics
Counterfeit bottle caps were made by some wastelanders inside the Cap Counterfeiting Shack. These caps can't be used or sold for any amount. They are found on a table next to quite a few Empty Nuka-Cola bottles and Empty Sunset Sarsaparilla bottles along with a couple full bottles of Nuka-Cola and Sunset Sarsaparilla.

Appearance
The Counterfeit bottle caps look exactly like a regular bottle cap. Even though it has the distinct 'nuka-cola' on the face of the cap.
