The set that dragged silver sales down the most was the 2009 DC & US Territories Silver Quarters Proof Set. Even though it has been discontinued a couple of weeks, its total retreated by -1,108. The previous movement was an increase of 1,647 which pushed the sets over the 300K milestone. The latest fall, however, caused their new tally to end up at 299,151.
