Sunset Sarsaparilla deputy badge

 is a miscellaneous item in Fallout: New Vegas.

Characteristics
The Sunset Sarsaparilla deputy badge is the prize awarded to those who can get at least 50 Sunset Sarsaparilla star bottle caps and give them to Festus to claim their prize. All of them are in a vault inside the Sunset Sarsaparilla Headquarters behind a door that only unlocks after giving the caps to Festus. In total there are 318 Sunset Sarsaparilla Deputy Badges, including the one that can be obtained by moving Allen Marks' body. It is possible that the badges themselves were the original prize, similar to promotions where soda companies would have consumers mail in bottle caps in exchange for small prizes. If this is the case, the "legal Constraints" regarding the "original prize" might be the Sunset Sarsaparilla equivalent to the "REPCONN Shakes".

The Sunset Sarsaparilla deputy badge is probably just a weightless, worthless and useless item.
