This is actually a good idea if it can be properly implemented. Of all the precious metals I believe Silver probably has the biggest upside besides maybe Rhodium. Everyone knows that chipsets and electronic connectors are gold plated. But most people don't realize that almost all electric switches have silver buttons of various sizes, then you have silver oxide batteries, and a couple tons of silver a year go into the exploding snaps that kids play with. The majority of this silver is simply discarded...how many people really recycle their watch batteries or pry the silver buttons out of an old hairdryer before they throw it away. As silver becomes harder to mine, expect sharp price increases in a few short years.
