Its only worthy attribute is the fact that its weight is 0 and it is worth around 7 caps. So basically its just like finding bottle caps except that you have to sell it. its typically found in bulk so you can make around 20 - 100 bottle caps per find. its a very helpful item to lower level characters as they probably cant hold a lot of loot so having weightless items is helpful. also it can be used as ammo for the rock it launcher and you can have lots of pre-war money since it does not weigh providing a realistic ammo source for it.
