Seems to me if you're not going to include chips the casino clearly marketed as millennium chips but didn't put the word millennium ON THE CHIP, you shouldn't be including chips issued for the wrong millennium either. Silver Club put out 2 chips at the same time. One says millennium and one says Y2K. Is this a 2-chip set, or was one an error? Are you going to split them into two sections of the list or drop one off? The Y2K Bug chip does NOT say millennium!

The only casino that beyond a shadow of a doubt got it right, you have listed as questionable. The Hilton chips say "Countdown 2000" but don't say what they are counting down to. The frame and all the advertising literature clearly does.

So now do we have a whole new category of error chip? Chips that commemorate something but don't clearly identify the commemorated event.
