I wasn't aware of this variation from Diamond Lil's in Renton, WA. The older chip is on the left. The decorative font is different as the older version has a much thinner bottom and the newer version a much thicker bottom (see the circled area). Also, now that I'm looking at them side by side I see that the diamond on the ace is also different. I'm sure there are other differences, but the text and the diamond are easy to spot.
