Introduction – Gresham’s Law

Gresham’s Law states that the bad money pushes out the good money from circulation. This is playing out live today for those paying attention.

Recent Historical Example Here in USA

In the mid-1960s, the US Mint, under the direction of the Department of Treasury and Federal Reserve, removed silver from dimes, quarters, and half dollars. Once they introduced the copper-clad equivalents (debased), the good money (silver coins) started being collected by the people paying attention (it took a while), and as the inflation of the 1970s intensified, all the silver coins were almost entirely out of circulation (into private collections) leaving only the copper clad substitutes for silver.
