TCR lists two varieties of catalog no. N4758. The differences are three:

One is light blue, one dark blue
One has a logo, one does not
One has both sides the same, one does not.

The scan below is from The Chip Guide, where it is listed as N4758.1 which according to TCR has sides with different designs, and doesn't have the casino logo. Only one side is shown in The Chip Guide, so I'm assuming the submitter found both sides identical. It does have the Dunes logo (at least the one I'm familiar with).

Two questions:

From the TCR authors, could the entries in the Obv-Rev and the Logo columns be in error?

For any collector who has these chips, do you have both varieties and are the differences as TCR states? Can you post a side by side scan to show the color difference?

I have only one variety and it's blue (can't tell if light or dark), same both sides, and has the Dunes logo with the Script D, same as shown in the scan below.

Just trying to make the information in these two guides consistent and as useful as possible for future collectors.
