I need to know when these two chips were released. Also, do you know if they completely replaced the old design with these or are they both being used at the same time?

The $1 chip in this design came out sometime around July of 2003. I don't think the above two came out at the same time, but I can't say I know for sure.

I would also like to get a nice example of the $25 in this design if anyone plans to be in Tunica in the near future.
