What kind of things could a person carry to sell and how if they ever had to forcibly leave?
I read diamonds are worthless second hand.
Solid gold seems legit but not sure if coins or jeweler is best.
I saw something about getting gold chains to trade individual links in a emergency.
Are there any other good tips?
AFAIK, in all anglosphere countries at least, the vast majority of asylum seekers are processed by border patrol shortly after entry, and they certainly would go through your belongings on the premise there was drugs or a nuke or something and find the gold bars.
