1986 Canadian Five Dollar Bill Serial # Question

As a rule, in general,for modern notes, if they're not listed, they are worth face value only, regardless of condition.
Due to inflation, your mom's notes are worth less today than when she tucked them away.
Does not mean they don't have any sentimental or nostalgic value.
You have to decide if they are worth keeping or not.

Welcome to CCF "Jpc"
It sounds like your mother had quite the collection. Sorting through it all can be quite a time-consuming chore and perhaps a little confusing. I suggest you borrow a Charlton (from your library) & perhaps check the site recommended by "John1" If it gets to be too much, you might just connect with a local dealer and see if they can help you out. Unfortunately, many seniors (I've met) have had no idea what they were collecting (other than it was old or being discontinued) so the likelihood of a piece being rare (valuable) is pretty slim but its good you're doing your homework as who knows?
If the Thiessen/Crow GNT is in perfect UNC (never circulated/pristine condition) it might fetch around $15-$18
The HNB or ANT Knight/Dodge are newer still so book around $9-$12
These are Charlton current Book Values for Choice Uncirculated so you have to take these figures with a grain of salt (hard to say what condition the note is in & what the demand is). On ebay these days it seems like the market for common notes is pretty soft (& you have to factor in your costs to list said items).
One generally does not send a note (or coin) for Third Party Grading (TPG: PCGS, PMG or BCS) unless the note is pristine and at least a little rare (special number, change-over prefix, replacement, etc) which those aren't.
Hope that helps answer your questions & good luck sorting it out.

Thanks everyone!
Found 2 mint copper bronze red colour 1936 pennies.
I know it's all about the dot, what would 2 mint uncirc pennies actually sell for?
One has the dot, which is slightly better as in no scratches etc... the other has one scratch hardly noticeable..
The dot is above the reverse flank side above the 9 left side.. The other has no dot sadly but are the sexiest pennies I ever did see :)
Thanks again folks.
