FIESTA MEDIUM GREEN
Why is Fiesta ware Medium Green so much more expensive than any other Fiesta color? Simple - rariety. Medium Green was only produced for ten short years (1959-1969).
Understanding Fiesta greens isn't tricky once you see a few pieces side by side. There are four vintage green Fiesta ware colors: Light Green (orignal green), Chartruese (50s), Forest Green (dark green, 50s) and Medium Green.
Here is a medium green cup (top left) next to an original light green cup. Probably the single factor that makes it hard to distinguish Medium green from Light green is that sometimes Light green has a heavy application and can appear almost medium green at times. (I have a tom and jerry coffee mug in light green that I can barely tell from my medium green). Many people refer to Medium Green as "John Deere Green". This seems as good a way to describe it as any. The light green almost looks blue next to it. The forest green is a dark green and there should be no problem distinguishing it
The middle Tom and Jerry mug in the front row is medium green. Forest green is on the right front corner and that's light green in the middle.
Here you'll see a whole collection of medium green Fiesta. If all else fails take your dish out next to the tractor and see if they match.
