Trade for Presidential Dollars, or buy?

JedM and I recently traded. I think he and I are now both looking for the same "P" mint presidential dollars, and can both trade "D" for them.

Here's what I am looking for: could trade for "D"s, or buy them.

2007 P : Wash, Madison
2008 P : Monroe, Adams, Jackson
2009 P : Harrison, Tyler Polk, Taylor
2010 P : Pierce, Buchanan
2011 P : Grant, Hayes, Garfield
2012 P : Harrison, Cleveland (93-97)
2013 P : McKinley, Taft
2014 P : Hoover
2015 P : Truman, Eisenhower, Kennedy, Johnson
2016 P : Nixon, Ford, Reagan
