If NGC graded all three 20th Anniversary Eagle Sets, why are all the coins not in the competitive set listing?
The complete 8 coin set of the 2006 20th Anniversary Eagles not just the 6 coins listed in the competitive sets list. This list the two coins from the A11 Gold and Silver coins the grading services have forgotten. The MS 70 Blue label is "The Rare Silver Eagle".
