Devil's Face Banknotes

It's rather difficult to grade a banknote based on pictures. It's best to have the notes in hand in order to properly grade them.
A couple options for you:
1. Take them to a local coin dealer and ask them to give you an opinion on grade/value.
2. Send them off to a professional grading service.
3. Charlton catalogues have a grading reference chart that helps you determine grade.
4. Try your local coin club or coin show.

Each option has its pros and cons.

However, for what it's worth, it's been my experience that devil's face banknotes are quite collectible and a great pickup at face value! Congrats!

Anytime you can pick up Devil's Face notes for FV is a good day in my books, nice score Enya.

and try to get a good estimate. The missing corner & graffiti do not bring down the grade but would be mentioned (& will lower what you can expect for them). They lower overall eye appeal but as @GMS5 points out - you get them for FV & that's huge.
