Some laminates have a glue residue others do not.
If they were mine I would try to remove the 1954 $50 note first (assuming it's nothing special) At least that will give you an idea what your working with.
You will always get at least face value for the notes and if not from a collector, or the bank, the BOC will give you face value for sure. Check out their website.
You could also just sell them on Ebay...I'm sure someone will grab them if your not ridiculously priced....if people buy shredded notes, why not laminated ones
