I saw in your last video that you had picked up some of these. They're nice-looking bars and should be something that if you need to barter for larger items, it should get you a fair amount of goods. If an ounce of silver is going to buy food for a week, this should be at least a a few weeks.
I am planning on switching to adding more gold next. I just have to have a few things happen in life and I will be in a position to move forward with that plan.
