I learned recently (CoinWorld Feb 16th) about the First Spouse bronze medal mule pairing the 2007 Abigail Adams obverse with the 2008 Louisa Adams reverse. These are present only in complete 2007 sets. I had ordered 3 sets late in 2008. I checked them and to my surprise, all 3 sets contained the mule. You can see that the Louisa Adams reverse is in the same sealed packet as the Martha Washington reverse. Does anyone know how many of these likely were made?
