American Eagle 25th Anniversary set: A slick marketing ploy
The set has two desirable pieces that our not available elsewhere: A 2011 S mint uncirculated dollar and a 2011 P mint reverse proof coin. In order to acquire these coins, we must purchase them in a set with three other coins (the W mint uncirculated, the W mint proof, and the generic mintmarkless uncirculated).
Veteran coin buyers are familiar with this marketing ploy by the mint. To acquire the 1998S matte Kennedy half, we had to put up with the Robert F Kennedy dollar. The 1997P matte Jefferson nickel was only available as part of the Botanical Garden Set.
