Gold, like most things man has based an economy upon, has no intrinsic worth beyond what we assign. While it is quite handy in the electronics industry, and the jeweler's of the world wish us to believe it's the only way to buy true love, it has no other real uses. In a collapsed society, items of real worth will be those that we can use. Unpolluted water, food, ammunition, any number of manufactured goods such as soap and toothpaste will be much more in demand than gold. It will be many years, if ever in our lifetimes, (depending on the severity of the situation) before gold is used again as a currency. Fishing weights and musket balls will be about all that gold would be good for.
But wait, you say. What about something other than a system-wide collapse, say a hurricane or other natural disaster of limited duration? Surely a stash of gold or pre-1965 dimes and quarters will come in handy then?
Wrong again.
While it is true that unscrupulous shop owners will charge many times the going rate for goods and services in such a situation, how many of them do you suppose will take your word on how much a Krugerand is worth? How many people, outside of coin collectors and survivalists, even know about the value of pre-1965 silver coins? And even if they do, how do you propose to buy a loaf of bread with a two ounce bar of gold? Take a wheelbarrow along to cart home your change in greenbacks? Far better, if you live in flood- or tornado-prone areas, is to have a wad of bills to supplement your food and fuel reserves. As I said above, anything that you use on a daily basis will likely be in demand after a disaster, whether man-made or otherwise. Soap, paper towels, toilet paper, vitamins, toothpaste and toothbrushes; all common, everyday items that we take for granted now which may be impossible to scavenge. And there surely won't be any more being made.
