I've also had quantities in purple; dtilled and undrilled. About $25 retail. The chip inserts are described as 3-3/4 sxsxs yellow/green/yellow. Which means if you were describing the chip without a scan you would be saying in has 3-sets od 1/4" inserts (colors) that are side-by-side-by-side. See Harvey's Guide to Collecting Gaming Checks and Chips by Howdy Herz. He wrote the language that so many of us adhere to when describing chips. It's basic and easilly understood. This is the official language used in our club.
