I discovered there are two different designs for the standard Paul-son sample chips that have inlays. The difference is in the mold style, the sequence of sales locations listed, and the size of the type used.

I'd like to buy or trade for samples that have the version shown on the orange chip below. Base color of chip doesn't matter but must have edge inserts and clockwise order of locations must be "Las Vegas Reno Atlantic City Gulfport".

It would be interesting to know which of these design varieties is the earliest. I'm assuming the style on the orange chip is earlier since it has the regular H&C mold, not the Reversed H&C.
