The chart doesn't mean much. The figures actually stay pretty steady until the drop in 2008, when the big recession hit, and the big drop in 2009 after everyone had cashed in their change jars to make ends meet resulting the Fed being flooded with coinage. Then in 2010 you see the number starting to go back up...and the chart ends. All the chart shows is a lowered need for production during the worst of a recession.
