Thanks mate, I didn't realise the new $1000's were H&C. Happy to go up to $100 but $500 or $1000??!! Don't think so!
I did see those new chips on the Sic Bo table. Sadly there was no one playing each time I walked by so I couldn't get involved and "palm" a couple. I ended up just asking the dealer before I left if I could buy some but the answer was as I expected!
