Hey Archie,

As a matter of fact, I worked for the Green Duck Corp as a graphic artist for about 3 weeks in 1987. Long story, but Green Duck Corporation is in Hernando, Mississippi about 12 miles south of Memphis, Tennessee. They make many $1 slot tokens (you'll see a GDC letter logo), as well as tokens of all kinds, medals, and pin-back buttons.

See ya,
Dave
