So my professional and presidency cents are on top of the Zachary Taylor and Sacagawea instead of being in their slots. Good job mint.
It really boils down to what you want to do with that set. Do you want it as a prime example of the year (2009) in question? Or are you going to cut it up and take out certain issues and place them in albums. I typically order three or four of the year (mint) sets. If this happened to me (which it hasn't in all the years that I've ordered these particular issues) I would use this particular set for "album fodder"....:smile However, I understand that there are collectors out there who can only afford to purchase one set, and that being the case, a scenario such as you describe is totally unacceptable....
