I know nothing about foreign bills so any assistance would be appreciated. I found this in with a stack of new and used US currency from many years ago. Thank you in advance.
ABNC made a whole variety of Mexican notes back in the day, and they all looked delicious. Fun fact, you can still use any Banco de Mexico banknotes (or rather, surrender them to a bank) for the modern equivalent, by knocking off three zeros from the end of the note. So you can technically exchange this old note for 0.001 pesos.
@hotwheelsearl is right; the American Banknote Company produced a large quantity of Mexican currency after the Revolution. Unfortunately, most Mexican banknotes are quite common but are quite aesthetically pleasing to collectors like myself. Regardless, if I had to guess, your note is probably worth a few dollars at most. https://en.numista.com/catalogue/note206957.html
These notes are extremely common, usually the kind of notes you would find in bargain bins at shows. As far as value I'd ask $2-3. As Bradley said, they are very appealing though.
The ABNCo made many different nice looking Mexcan notes. Mexico produced some interesting contemporary notes. I got many more interesting Mexican notes I'll post if I can find the image files.
