because there more common than normal paper money
bottle caps
You need 50 Sarsaparilla Star Caps to proceed to the next part of the quest.
There is no one specific place that has a total of 1 million caps but if you play it long enough and trade enough I'm sure eventually you COULD reach one million caps if the game permits you to do so.
A home brewing supply store will carry bottle caps.
In my opinion Fallout New Vegas is. In Fallout NV it is easier to make caps so you can buy better wepons and ammo. In Fallout 3 It's hard to make a lot of caps in the begining making it a slow start. But is you want to test your skills play Fallout 3.
There are many companies and websites that offer retro bottle caps that are from the 1950s. Some of these websites that offer bottle caps are The Bottle Cap Museum and Northern Express.
You can sell your stuff. Or you can kill people to get it. :)

Firstly you only need 50 blue star bottle caps and once you complete the quest you can find a room with a unique laser pistol called "Pew Pew", though strong it only fires 2 shots before you have to reload.
This is a long quest but a Good story. You will need 50 Sunset Sarsaparilla star bottle caps before he gives you the Prize. These can be found in many locations, aswell as a few being won from Festus in the game 'Lucky Horseshoes' which can be activated Via Speech with him
