I'm waiting for the day the apocalypse strikes and fishing hooks and line, Band-Aids, toothpaste, needle and thread, silver, good knives, scissors, disinfectant, bollerwagon's and the like become the currency...Oh, and survival skills. :)
Let's see how long cash lasts; You, at least, are young enough that it possibly won't last your lifetime.
In that case hollow points or match grade rounds become currency. What's a bollerwagon?
Precious (or just useful) metals have been 'cash' for thousands of years, I'd be willing to wager that the same would hold true even after the apocalypse.
A bollerwagon is one of those pull-carts people have, you know, a load area with a big wheel at each corner and a long shaft; The front axel is on a swivel for easier steering. I think bollerwagon is the what they are called in Germany and we don't call them that, but whenever I get the chance to insert bollerwagon into a comment I do so. 😂 Google bollerwagon then hit images and you'll see a bollerwagon. OK, so I count 5 bollerwagon's, six including that last one. That's enough bollerwagon's for one comment. Oops, there's the seventh. 😆 Small things amuse small minds mate.
Yep, ammo, guns, cleaning equipment, ammunition components, sharpening stones, paracord etc...All good currency in the right circumstances. (Useful metals too as you say.)
P.s. Bollerwagon
