I took a few minutes and checked TCR. By the way there are more listings since last time I looked. Here's an example:

"Casino Chip OBS Dunes Bac LV $20 Reno Lucite"

Listed as $200 chip in my TCR, so unless the bottom fell out, many of these are $60 and up values.

Now we need someone who knows how to remove a chip, without dammage. Maybe someone who does chip restorations... Nevermind!
