Rich not the purple I have seen. This is a tough one its lavender I think. The pinks that are common dont look pink though but I know when Michelle Burke found them the box was marked pink & the others brown.
Yes I do think these Christmas are very valuable as a Reno chip with Tahoe borderline so some of the Tahoe big buyers might push the prices up.
Yes the lt. green went around $650 on ebay & then privately the best next to mine was $700. One I have now has just a little use & was not one of the best.
I have not even seen these LVC chips. Problem with these is they are not that exciting therefore I think Cactus is still the best. Christmas second. $1200 though is a bit extreme for a grey one of two known. If unique they should book with a premium. Once that status changes I usually drop a chip 40% to 50% unless something really great like a Sands arodie $5. With a few of that one known it is still very valuable as huge demand.

I will refer to your website for info. to list chips next book. You have a great site & I do look every now & then as I really like the C&S chips.
I dont have the El Cortez or others.
