Unless you understand the reasons for a gold or silver standard, the argument over the content of coins (what used to be actual money) makes no sense. When government dictates what is money, it should make that money out of the cheapest materials available. The dictate is the sole source of value. When people dictate what is money, the content of the coin determines its value. The government just guarantees that content by stamping its seal on the material.
When people re-assert their sovereignty and once again demand that one dollar be one ounce of silver, no matter what the government says, a lot of our problems will be resolved.
