1,000 made.
You know where I got mine.
As you know the buy-in chips were worth $500 to poker players. They were kept in the cage and accounted for. After the last Rio tournament 998* were in the cage and accounted for.
You will have to ask Harrahs where they are today.

* I am using 998 because I can't remember if I might have gotten 3 or 4 of them. Its possible I did and traded them. Geez, that was 6 years ago!!
