There really is no difference between a silver coin and a paper dollar. They both have the same practical use, which is a fiat bartering tool to exchange for real goods.

You might be able to fool some people longer with silver coins, or even gold jewelry and diamonds, but it's all worthless in the end.

Fiat bartering tools are for fools, and crooks.

Skills, water, food, shelter, tools, gardens, etc., are real.
