I've been reading the comments and have to ask: "If I had a stash of food, water, generator, and other goods, why would I sell anything for metal coins?" Unless I were sitting on a mountain of goods, why would one sell? Metal might be good for a store of value AFTER the emergency, but I do not see the value for purchasing goods/services during the time of disaster--sure cash is good short term, but eventually people undestand that they cannot eat it.I live in Louisiana and I have been through many hurricanes. We have lost power for a week or so and data lines often get damaged so the stores that are running on generator will only take cash. So for a natural disaster, you need cash. No store will accept a piece of gold or silver. Now, in a complete breakdown of society where we are all trying to scrap up resources to survive, both cash and gold would be worthless to me. A shiny rock will not feed my family. I would be going by the barter system.
In 2016 we had a major flood in my area where 90% of all structures took on water. There were very few stores open in the area right after the flood and the stores that were open were rationing what they had. Luckily we keep a medium size supply of shelf stable food on hand so we were ok for a week or so until we could get out of town to restock. During that event, if someone had offered me cash for some of what I had, I would not have accepted it. We had enough food and supplies to survive on short term, but not enough to sell and share. You cannot eat cash or shiny rocks.
I like the seeds idea, but how long does it take to obtain produce? What if the emergency is during winter?
I have a modest supply of food, a water filtration system, some metals, and guns with an appropriate amount of ammo. SO, what do I do after the first few weeks?
What about the people who live in large cities?
Other than leaving for farm land, where are you going to go in a vehicle? Why would car repair be a particularly important commodity? Have any of you northerners been through a gasoline shortage? Assume EMP, no gas pumps, no electronics, and PANIC. I can tell you getting gasoline will be a major problem; additionally, what about getting stranded in the middle of no where in your car (during a snow storm). I'm sorry, but I just do not 'get' it. Please explain.
