I've shot loads that I made with primers that were from the 70's. Some may have been from the 60's.
All went bang without a hitch. Primers don't go bad unless they are put in an environment that induces them to go bad. Take a look at them - if there is no corrosion and the boxes don't appear to have been wet at any point, odds are extremely high they are perfectly fine and you came across a great deal.
