I have a black diamond all-time greats championship rings insert card.  The card is of Denis Potvin.  ATG-12.  On the back at the bottom it says it was from the 2011-12 set.  But I also have the Mark Messier on ATG-12 that says it is from 2011-2012.  So does that make the Potvin one an error?

According to Beckett, the Potvin should be 12-13. Could be a misprint, or one of them was supposed to be in the prior year and was an update?

All the 12-13 all-time greats championship rings have the wrong year on the back.
