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?
Seconding this. The best money is still money.
If you can’t get a good stable currency or you have legitimate fears that the currency you can get is in danger of some kind of collapse, gold or silver coins would be your best second bet. In this case you’ll want well known coins minted by an actual government such as an American gold eagle or the Canadian silver maple leaf rather than the coin shaped “rounds” that a lot of places sell. The rounds will have the same issue as jewelry, you’ll have to haggle over weight and quality every time you sell one. Actual coins issued by a government mint will have pretty well established values so they will be easier to sell at a fair price.
