My guess is that she didn't know the chip had any value since Atlantis has been closed for some time now. Many folks not familiar with the hobby do not realize that chips from closed casinos have value. Did you read her original post where Cheryl asked; "I recently found an old chip from the atlantis in ac. Wondering if it is worth anything or if I should just make a key chain out of it?"

I stand by my reply to her post.
