Where Do I Start? New To Collecting Bank Notes

to the CFF, Kgirl! First get the book. I'm not familiar with Canadian or world currency, so someone else will have to help you there.
As for values, check ebay sold listings or other auction sites such as Heritage and Great Collections.

If I were you, I'd take the link that automatically appears in your first post once you wrote the word inherited. It gives some great advice on how to tackle the steps you need to take. Scroll down to "Some More Tips..." & read #5, #2 & #3 again (if you haven't read them).

I would not worry to much about grading at this point but more in terms of IDENTIFYING & documenting what you have. Get organized. A great place to start is to get a catalogue but if you wish to look over some & get a general idea (before you buy the catalogue) try checking out what coinsandcanda have:

Remember to take your time & take lots of breaks since the whole task may be a bit overwhelming. Use a notepad to make notes once you've identified a note (remember to write down its code like BC-7 for the 1935 $10)

Take the BANKNOTES link to further investigate notes from the Chartered banks ("Banknotes of Canadian Banks") like BMO, TD, CIBC, etc if his collection has those & the Dominion link for "Dominion of Canada" notes).

Keep reading & learning from forums like this one. I posted a thread that gives a general breakdown plus a few helpful links to grading (you may find helpful) after you've sorted out what you have. Check this NUMISTA site out which also has a good Bank of Canada catalogue of notes to help ID what you have.
