Grecon IV is a class M world in Cardassian territroy.
In 2377, the USS Ottawa performed a survey of the system and discovered interference when attempting to scan the planet. Captain Jenna Carson, along with Susan Cassoday and Sonya Fiehrer, surveyed the surface in the runabout Verdigris.
The survey team identified a large deposit of duranium. Because of the importance of the deposit, the Ottawa crew agreed that the planet would be of significant importance to the Cardassian economy (USS Baldwin: "Like the Rain")

The name of the planet is a tip of the hat to The Price is Right producer Kathy Greco.
