Missed yesterday due to travel -- sorry. As a bonus, and to help me out, we have a multiple chip day! These chips are from the Horseshoe Club in downtown Vegas. All 10th issue, book says release in 1960's and 70's. Thanks in advance for any help with sorting out the chips below.

There are 2 $.25 brown chips in the TCR, one Dk Brown (N1767), the other Rust Brown (N9972). I have the 2 chips shown below. There is a noticable chip color difference, but not enough for me to be sure that it is a different chip. Besides, I'm not sure I would know 'Rust Brown' when I saw it. Anybody out there who has both chips and can straighten me out?

Similarly, there are 2 purple $.50 chips in the TCR, one Dk Purple (N1776), the other Lt Purple (V2809). Even though I can detect a color difference in these chips, neither are as light as the example in the visual TCR, so I suspect both of these are the Dk Purple variety. Anybody out there with both chips who can confirm?
