All the chips that you show are back up chips and were never used at the tables. The Rack chips should be:

$25 Green and White not Green and Pink
$100 Black and Orange not Black and yellow or red
$500 Purple and Lavender not Purple and Light Green

To the best of my knowledge no rack chips of these denominations were found at the dig in MS.

If you do have any of these rack chips they would be worth a lot more than face to Playboy collectors.
