I bought several lots of Dealer School chips in Doug Saito's auction in Las Vegas. In several cases I had some colors, but needed to fill in with the others. The chips sold for from $5 to $50 depending on whether they were in multiple-chip lots and what kind of bidder competition there was.

Here are some dupes I have. You can have any of them for $7 delivered, or all 9 for $50.

The green Casino Gaming Schools, Inc. chip is marked $25 on the reverse. Doug's catalog listed the location of each school and I can provide that info if you're interested.
