This is a green, Anchor Hocking, Colonial, aka Knife & Fork pattern, coupe soup bowl. This pattern was manufactured for only two years, between 1934 and 1936. This piece fluoresces when placed under a black light.
I have seven (7) of these soup bowls available for sale, each one separately. They are all in very good condition. There may be some light use scratches on them, but they are still nice.
Take a look at the pictures, and if you have questions, please e-mail.
