Why are promotional chip is notched?

I’ve seen a bunch of these on eBay recently, probably from the same seller. I’m sure there’s no good answer for this.

Same reason as why some chips originally purposed for casino use are stamped, drilled, and notched. Except not really.

Chipco would sometimes use an actual casino chip image on one side with the Chipco logo on the back. Since the image on the casino side was the actual image submitted by the casino and could be passed in the wild as a negotiable casino cheque if an employee didn't review both sides, those samples would need to be drilled or notched.

For the chips above, if both sides are the Chipco logo, in that case I'd have no idea. Practice, perhaps? Boredom? *shrug*

If they have the same edge designs as some casino chips they could be passed off as that chip in a stack of them, so they would notch it to avoid that.

To prevent counterfeits. This video doesn't explain notching, but is a good documentary of two guys who were successful at casino chip counterfeiting. That was until on guy told a girl about the scam. IDIOT! This is only a snippit. The full video I can't find at the moment.

You are correct. No face value = no reason to notch = no reason to counterfeit

They're not.
Also, I'm not sure what was happening with my brain when I typed that subject line, but it cracks me up and I'm leaving it.
