The note itself is a "Devil's Face" which makes it more desirable than a modified 1954 series note. You wouldn't find 10 of these uncirculated in sequential order for $100 for sure!
It is hard to grade banknotes from photos but it does look like it could be VF/EF.
One in VF condition with this prefix sold on ebay in November for $42 but yours looks better than that one.
Canadian Coin & Currency had an AU50 listed for $174.95. There is an EF40 on ebay for a B.I.N. price of $100.
I don't have my Charlton Catalog with me right now but will check it when I am home later.
Based on this, I would say that your mother's note would be obtainable at around $75-$100.
