Canadian Tire bills - worth anything more than face value?

I was given a family member's C-T money a while back and sort of forgot about it till tidying up recently. Some bills go back to the early 80s, is there any chance any of it is worth anything more than it's face value or am I best taking it in and getting it added to my card account? Thanks!
