Paul, they talk about it on the Hollywood Park website. This is from the Hollywood Park Web site: I really hope they made a typo on the $8 plaque!!!

The chip set will consist of an $8 plaque design (Production run: 188), $5 octagon design (Production run: 500) and $2.50 octagon design (Production run: 500).
Stay tuned for the release date in early February.
