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?

Edit: Put in a Consolidation effort based on comments and side research

  1. Jewelery is good getting through customs as some countries have limits on what you can take over borders. Canada for example has 10k limit before you have to delcare and it is not clear if per person.

1.a) Always buy jewelry you plan to wear anyway because you will not get full value back.

1.b) Buy from reputable locations. Looks like Mene was a popular one.

  1. Gold coins are good but get normal ones like Eagles, Buffalo, or Maple as it’s easier to sell. Fancy ones are cool as collector item but will require more haggling.

2a) Bars are cheaper over spot but can be harder to sell overall

2b) Seems like libertycoin had consistent reviews.

  1. Cash is light but if your origin country currency dips then it’s worthless.

  2. Crypto requires you to have your wallet seed and importantly access to a pc and electricity.

  3. Make sure to have a backup skil/trade to live off of.

  4. Transferring money between banks can have legal issues.
