How many silver dimes would it take to buy 40, 80 or 160 acres? A milk cow? Or maybe a solar power system when TSHTF?
I would think in most scenarios that land would take many years to start selling again as we know it today. In fact, land may be the thing that is readily available due to the fact that so many people could potentially die off from starvation, violence, disease, etc. As far as milk cows (and other livestock) are concerned I would venture around $20 fave value of silver, but who can really know. Ammo and other goods are your best bet there I would think.
Solar Power? If its my system I guess I'd give it up for one bullet, but you would have to put it between my eyes when I was't paying attention....
