And what of Gresham's Law, the tendency of "bad money" to drive out good money?

In a private system, good money – like good products and services in a free market – outcompetes the low-quality money. In a market-based money system, there is an inexorable tendency for good money to win out.Now think of gold or silver in Zimbabwe.
