OK thanx i'll stop hanging on to it because i need the caps.
You can make a few quick caps by going to the Market next to Megaton. Take a merc with you after you clear out the raiders load your merc up with all the cans and pre war money you can find and sell it to the merchants for some quick caps. Also you can drink nuke cola to get a cap off the bottle not to mention some Health Points just keep an eye on your Rad meter
