These notes are Chartered Bank issues. They are published in a separate Charlton catalogue titled "Canadian Bank Notes". I only have the 6th edition. I believe there is a newer 7th edition.
1920 - $5 Imperial is a cat # 16-06, 6th edition shows the highest grade of EF @ $1,700
1935 - $5 Dominion is a cat # 26-02, 6th edition shows an Unc price of $900.
1935 - $5 Toronto is a cat# 24-02, 6th edition shows an Unc price of $1,100.
Someone else may be able to verify current pricing.
Hope this helps.
