I did this scan a few years ago to show the differences in the three SMCRWN dimes from New China Club. The salmon one on the right is common as dirt; most are unused, and it's almost like someone reordered the red one, they used the wrong color clay, the the chips went into someone's desk.

The red one in the middle is quite scarce. The red one on the left with large chinese characters and no denomination on the obverse is almost impossible. I've only seen 3 or 4 in all my years at looking a dealer books at the shows. It's a first issue from the 50's and a Rarity 9 in James' catalog. Both red chips are undervalued in TCR, in my opinion.

I may have extras of one of the red ones but can't put my hands on them right now. If they show up, they will be in my trader book in August.
