Canned meat can be stored a few dozen years. But I guess if that was a question, you should better care for the safety and preservation of your ammo...
Yes but you want a very
value-dense material, in the sense of most value / less volume (m^3)
So the best thing for that is
diamonds, not gold. Diamonds have the most value / less volume, so i dont understand
why you go with gold.
Unlike diamonds, gold is divisible, and, what is more important, gold is
standardized, that is, a given bullion of some purity is not much different than other such bullion of the same purity. There are no two diamonds that are identical and valued
identically, hence raises the difficulty in assessing the value of a certain diamond...
In short, no one will care for diamonds when canned beans become the staple of one's diet
