Wynn, like all the bigger poker rooms, has multiple sets so they can have different events running in the same room at the same time. They have a dedicated satellite set also. I seem to remember four different sets.

Agreed, I did see that there are different series of Wynn tourney chips. It's just that the particular chip I have seemed to belong to one particular series with the same inlay, only that the color didn't match what I've seen of live chips in play. But Ross cleared that up for me, thank you both!
