Jim, this is what I have from the "vault of Ted" - "I really don't recall the different colors of those tip chips. I know that it was a unique concept and I'm glad that you have discovered chips that even I do not remember."

Now, I do believe that I have an email from years earlier (I have about 50 - 100 emails between Ted and myself) and I think he explained the "colored Tip Chips". I'll see if I can find it (I don't toss my old emails).

What is odd about Mark's Chip, it looks like it's 2 different colors (red on one side, blue on the other).

I've seen, Chip colors in Yellow, White, Blue and Pink.

It has value to about 3 - 5 of us so I wouldn't know where to begin with the "value" is on that chip.
