It is known that Commissioner Pete Rozelle stopped signing the NFL checks in March of 1968. The lot contains two checks one signed by Rozelle dated March 11th and one signed by William Ray dated March 15th. Somewhere between the two is likely the last Rozelle signed check. Technically it could be this one as we haven't been able to find the exact date he stopped, but this would certainly be among the last. Rozelle check is CAS certified
