It has been my feeling for at least 4 or 5 years that our nation and the whole world for that matter is rapidly approaching a major crash of some sort. That crash will of course include currency (of each and every color) but more than that it will include food, water and medicine. The crash is totally un-avoidable and no place on earth will be exempt from it. Paper currency could become completely worthless. My wife and I decided 40 years ago to buy up as much pre '64 "junk silver" (dimes, quarters, half dollars & silver dollars) as we could afford and stash them away. Keep in mind if you plan to buy some needed materials with the silver, use only the smallest change you have available because you won't get change back. Twenty two (.22) ammo I'm sure will be a wonderful medium of exchange, much better than centerfire ammo. So if you have similar thoughts as I have about the direction the world is headed pick up as much junk silver and as much .22 LR ammo as you are able.
