From a label on the box they were packed July 24, 2015. Not sure if that is a kill date but only one I see on the box. Also looks like the box was delivered to the Elks in Sept. Where the cryovac usually has "choice, prime, or select it just has the "Chairman's Reserve" logo.
I just took them off the Club's hand because he didn't want an odd box of something he doesn't use. I paid his cost of $196 for the box of 71 lbs. Little on the expensive side but they look pretty good. Walmart has select/choice here for $2.49.
