Someone I knew who had direct experience with crisis situations said whisky and cigarettes are the currency of choice when things get serious. He said a stockpile of those items would allow you to pay the thugs with guns you needed to stay safe.
Can confirm, whiskey , cigarettes and women are currency when a country goes Zimbabwe or Kosovo. Here in America add in 22lr and 9mm ammo worth their weight in silver for sure and gold if things really get bad.
