There are four chips in the Chip Guide....The first two are both different because of what is written on them. The other two in the Chip Guide are similar to mine in look and color, but mine have the same lettering of the fir two Orange chips. I think the yellow chips (mine) are an in-between change in chips from the Orange to Yellow, but the type was the same as the Orange. Here's the guide entries.
My chip does have "Club" and the ones that look like them do not have "Club" but just Harrah's.
My scanner is correct, and calibrated for exact color. Plus I use Adobe Creative Suite that has been professionals calibrated.
