The US Mint has added release dates for the Grand Canyon (6/29) and Mount Hood (7/28) P 5 ounce silver ATBs: http://catalog.usmint.gov/webapp/wcs/stores/servlet/ProdschedView?storeId=10001&catalogId=10001 TC
I'm guessing that means the 5 coins that were REALLY supposed to be released this year will begin at the end of August and continue each month through December.
More then likely, which means unless I hit the lotto or the 2010 UNC's skyrocket in value I don't know if i'll be able to keep up with the 2011's from the mint... Add on the fact that I would really like to get a 2011W Gold Eagle and this year is getting really tight.
The release date of the next hockey puck is the day before the release of the silver eagle proof coin. It should be a couple of busy days at the mint.
