Apparently they were being shipped from the Philadelphia Mint to Florida, but someone got to them while the trailer was parked at a Walmart in the Philly area. It was apparently carrying about $750,000 worth but the thieves only got a fraction of them and many were strewn over the lot. I heard what was actually stolen would have weighed about 5 tons.
