In December 2004 Atlantic City Chip Collectors were getting a flurry of LE chips.
The good ole' days...

Bally's and Caesars released 25th Anniversary chips the end of that month on the same day.
The Caesars chip is a hologram and I heard the Roulette machines were doing a number on them rather quickly tearing the hologram off of them.

Both of these chips are in NEW condition.
Selling them as a pair for $15.

Email if you're interested.
