[QUOTE="bhp3rd, post: 839762, member: 16510"]Just as a bit of history if you will I looked it up regarding mass quanities of silver that have been used. Oak Ridge borrowed 15,000 tons, or 30 million pounds of silver from the fed, (yes those number are correct) to make wire during the WWII because of the shortage of copper. It says all was returned to the fed afterwards and I'm certain it was, (when pigs fly)! Just a bit of trivia, article below.
