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?
Not a topic I’m super familiar with, but I feel I’ve heard people often are either robbed or have their items confiscated by authorities. Same with unhoused people not wanting to have stuff that would make them a target.
If it was something you had a little bit of prep time for, ziplocking USD or EU and seeing it into a grubby jacket where the repairs would blend in and not garner attention would be the most portable and effective thing to do while minimizing theft potential, other than having all eggs in one basket unless you split it between different garments. Also make sure it is pretty weatherproof to prevent mold damage.
It also has the benefit of being immediately usable, should you need to pay for transport or food. If it was seen in a puffy coat, one could discreetly remove one pack of bills while leaving the rest secure. The immediacy that cash can be used may make up for having something potentially more valuable that you would have to barter or fence, as pretty much any human has a need for cash.
To add that secret compartments in your accessoirs.
My sling bag for example has 2 velcro pouches on each side of the band. You would think they are sewn shut but on closer expections they are actually vecroed.
Using it as a emergency storage for some coins. Helped me once already.
Not putting in a link until requested. No need to advertise :)
I think I actually had a coat once with a hidden pocket like this that I didn’t know about until I had it for quite some time! It wasn’t big enough to hold a lot, but it was a very secret stash. Even some coats I have with inside pockets blend in very well, but those probably wouldn’t pass someone searching me at a checkpoint of any kind.
My pouches are a sort of faux leather type of material. I couldn’t fill it with anything bulky but I could certainly get a small stack of 200€ bills inside without being bulky.
