If you look at the seller's response to a question, you get this:

Q: This chip isn't live right? Not cashable? Just for collectors?
A: Hello and thank you for your interest. This chip is being sold for collector purposes only. To the best of my knowledge, Casinos in Las Vegas will only cash chips in denominations of $1000 and higher if you can prove through surveillance and/or management that the bearer won in the casino. Please do not purchase this chip with the intent of cashing it in. Thanks.

I believe there is also a question as to how many of these $5000 HR chips are out there. Too many seem to be showing up....
