Don,

That's how I listed it in my guide, but that isn't really the problem. There are literally hundreds of these little designs in the center of roulettes. Usually, it is fairly easy to give them a name, but sometimes that causes confusion between different collectors.

For example, I call this design "propeller", but I know of another collector who calls it 4 Diamonds.

Another example, I describe all of the chips below as "pinwheel"

There are many, many more examples. I am positive, that in many cases, these are stock designs the manufacturer offers to the casino. I am sure they either have a name or a number, much like the stock design a bank offers for imprinting on a check.

If I had the official designations, I could refer to them as such.
