Is there any difference between the 2011 W Silver American Eagle Purchased From the US Mint in 2011 and the 2011 W Silver American Eagle Inserted in the 2011 25th Anniversary set? or are they the same?
They are the same. I think I recall that NGC would attribute all of the coins in the boxed set as 25th Anniversary only if they were delivered to them in the unopened shipping package. They were concerned that some unscrupulous people would switch the coins with ones purchased individually. The same was true for the 20th Anniversary set. I don't know about PCGs. Chris
