Couple of questions, David.

Have you ever seen the Sahara Tahoe with lavender inserts? I think it is a ghost color resulting from different descriptions from two catalogers.

Have you ever seen the Monte Carlo Reno no-inserts chips uncancelled. I haven't. I think all of them are drilled although TCR lists it as very scarce.

Same question on the Monte Carlo with inserts. I have never seen one without the overstamp cancel on one side. Have you? Mel or Armin should know as I believe they got all the chips from the owner.

How about the Primadonna purple H&C with no inserts; seen one? TCR does list it as extremely rare.

Sundance CIC. I've only seen this with a coin that has concentric circles. Seen one that's smooth?

I'm guessing that all the others you list do exist, although I don't have them all either.

Good luck!
