I found this in a used copy of J.D Salinger's Nine Stories. I had been looking for a copy of the book for an essay I had to write for university and found this tucked in the back with an old bus pass.
Here in New Zealand $5 should be good for a substantial 3 scoop icecream cone. Not sure if it'll get you much in the way of drugs. I'm sorry to say it was used for neither.
