But what if the crest and seal chips were from Vegas?

Example: Recently, a green and orange Dunes roulette c&s sold for $1875 and $1950 on ebay. I don't know the population but I would say less than 5 of each.

However, the exact same Dunes roulettes only this time the colors are brown and salmon sell for $75 to $125. Why so little? A box were found of each.
