Why would that help you in acquiring them?
They are all in the cage.
They will probably never leave the cage.

That said, I need to elaborate.
The 5 Grand Sports Book chips are still in play
There have been 3 different 5 Grand House chips (including backups) and one is still in play.

None of the chips have ever been redeemed, just removed from play. They are still live chips.

Probably only 3 or 4 of each ever existed notched.

There is also a 1000 Sports Book chip
