Very confused here

The chip guide here shows a pic of a light blue chip that is suppose to be N4764. Light Blue with a Dark Blue Inlay.

The chip rack says that N4764 is blue with a gold inlay and that N1790 is the chip that is Light Blue with the Dark Blue inlay.

On top of this I just saw an auction for a $1 with Las Vegas, NV on it with a square logo that is Blue. Is this a new chip? I thought the house chip was a dark gray.

Needless to say I am totally lost here.

So I need these scans

The Light Blue with Dark Blue inlay, Rectangular Logo, and what is the correct TCR number.

The Blue with Gold inlay, Rectangular Logo, and it's correct TCR number.

A scan of the Light Gray chip with Rectangular logo, and it's correct TCR number

A scan of the Dark Gray chip with Square Logo. I believe it to be the only one with Las Vegas, NV on it. And, it's TCR number.

And finally what I assume is the new chip. Blue, Square Logo, Las Vegas, NV. I have never seen this chip before except for the auction I mentioned earlier.

Oh, and a scan of the $.50 1980 yellow chip. I have never seen on before and am curious what it looks like.

Just a note. I would only be on the market for the dark gray and blue Las Vegas, NV chips. The others are priced beyond my finances at the moment. Still trying to collect currents for the moment. I which I am missing tons. I should be busy with that for a long while.
