Hi Scott, Here are the variations I have of the plain hat mold design. They all have the little injection nibs or depressions on one side but, not the other. The top two in my photo have the same weight and feel but, the white chip has a groove around the center while the Caesars chip is simply a depressed center. My bottom blue chip is a very light plastic chip, not anything like the top two. I collect variations of manufacturing and would like to get one of your chips that has the nibs that are really sticking out
