The Stardust black/3 pink/3 white that I have is dated 674. There are 2 Paulson metal-inlay varieties listed in TCR as 1976 chips but since I've never seen the other, I don't know which I have. The one Alex submitted to The Chip Guide appears to also be dated 674. I've submitted a hi-res scan of my chip to The Chip Guide for clarification. It's shown below.

Anyway, TCR should list one variety as dated 1974. It would also be nice to see a scan to learn what is meant by "large rim" and "small rim" in the description. By the way, TCR listings show value for a SU chip! They must have been collected a long time ago to get them that good .
