Could be Annual Inventory. I've had a couple orders in , one for a couple weeks. Counting all those coins could be slowing them down. Whenever I have a lot of coins to count, I take them to the grocery store and put them in the coin machine. I exchange them for a Starbucks Card, no Fee.
"Due to the United States Mint’s annual inventory, expedited shipping will not be available for orders placed from September 5 through September 14, 2008"
