I still believe precious metals have value, most of my investment there within has been in lead & brass. I don't believe it's if society collapses but rather when. It's feeling a lot like we're living in what I've read the roaring twenties were like, I suspect October 29th 2029 should be a fun day! I actually don't think at our current acceleration toward collapse that we have that long.
The barter system will have to be weighted some what, a skill surgeon's time, just like today will be more valueable than a skilled goat herder's time. A skilled goat herder's time will still be worth greater than 10X that of a Cisco systems administrator or financial advisor. Antibiotics will be worth more than plutonium by weight. Those that can fix and build things with hand tools (or pneumatic powered by windmill driven compressors) and field trauma doctors will be akin to our Warren Buffetts and Jeff Bezos. 1 good mule will be worth more than 10 Kenworths, a good bicycle will be worth more than a 2500sqft house. Axes & crosscut saws will keep people from freezing (that know how to use them). Deer over population in suburban areas will no longer be a problem.
Things are poised to look very differently in the next 5-7 years. My oldest chooses a foreign language to study in middle school next year, the choices are between Spanish, French, Chinese & I believe German. I like to pick winners, guess where I'm going to direct him.
