Yes, if I were to sell it, I would first have it certified. Thanks, walktothewater, for the reference. For the time being, it's filling my Macklem/Carney spot!
And, in reply to Archey80, I checked it out more closely because I just didn't see the point of putting up a regular circulating note for auction, even in reasonably high grade (it is very lightly circulated).
Ah, and I always forget to point out that if you look closely, the "2" on the right side is slightly higher. This may be part of the reason why there's a mismatch. Also, it would mean that the same kind of equipment is used for serials numbers on polymer that was used before 2011 (the possibility that it had changed with polymer was suggested in another thread).
