That opens up a serious topic of conversation.
In what post-collapse economy would silver be of value in, when the profitable market to trade it in has gone ?
It has no value at all until a very long time after the collapse is recovered from.
That's not meant sarcastically - I am always curious when folks raise the subject of precious metals and similar 'valuables'.
Any serious collapse would suddenly assign huge value to skill sharing (doctor, dentist, crop and animal farming etc), cooperation and the resources for immediate and long-term living (note my avoidance of the word 'survival').
It would be a very long time after a collapse is recovered from before silver would hold any value.
Imagine the scenario:
Hungry guy: "I'll give you a kilo of silver for that deer you're dragging back to camp"
Bushcrafter: "Bugger off stupid - what the heck am I going to use silver for out here ?"
All joking aside, my biggest fear would be when the thin veneer of civility that masks a human being's baser nature is stripped away. Any serious upset in what people view as the natural order of things would see people turn on one another in a second if it meant they could eat, ensure their ongoing survival and so on. I don't much care to be caught up in the middle of that
