Value Of These Canada $1/$2 Bills

I have been asked by a friend to look into potentially selling some older Canadian bills that he had inherited if they are of any value. I let him know I would do some research but I am not very knowledgeable on bills. All of the bills seem to be in mint uncirculated condition with the exception of one of the $2 bills that has some kind of an ink stamp on it. Any information would be greatly appreciated.

There is a stack of 25 of these 1967 $1 bills with no serial number. From what I have read these would not carry much of a premium if any at all.



Next up are the $2 bills. These ones carry the EGS prefix which don't seem to carry a premium individually. However, they are all in consecutive order from 3893550 to 3893584 with the exception of 561 which seems to be missing.



Another set of 2 consecutive notes



And a set of of 9 consecutive



This one has what looks to be teller stamp on it and a very slight crease on the bottom right corner.



And the final 4 bills have various serial numbers that I do not think would be worth any premium based on my research so far.
