Those chips were still in play until last year. Even after the rebrand to Caesars, the Harrahs NCV and WSOP Nola chips were still in play until the new Caesars WSOP chips were made.I just watched that, it looks like they are still using the chips from this sale in the 2006 events.
Very cool to see these chips on that ESPN coverage with Lon and Chad.
Sometimes, tournaments even mixed the two sets.
The last two photos are the current Caesars house NCV and Caesars WSOP. I imagine those will fetch a pretty penny in 20 or 30 years when Caesars is bought out
