Sunset Sarsaparilla Star Bottle Cap

 is a miscellaneous item in Fallout: New Vegas.

Characteristics
The Sunset Sarsaparilla Star Bottle Caps are found throughout the Mojave wasteland and are a collectible item. Some time after the Courier finds a special cap (one can be found in a house in Goodsprings, a man named Malcolm Holmes, a retired cap collector (though he has six star caps), will approach the player and warn that the caps are highly sought after by collectors who will kill for them. The caps are thought be very valuable, because according the legend they allow access to a secret treasure guarded by a man, since before the war. They are apparently still occasionally found by opening new bottles of Sunset Sarsaparilla, as the man guarding the treasure distributes them randomly.

Locations
There is one bottle cap located in Goodsprings in a building (labeled "Goodsprings Home") a few yards just southwest of a rotating windmill on one of the counters inside. (Possibly in the kitchen.)
