Hi Michael,
I believe that you will read that "The Official" guide values this chip at 100-200-400, with 200 at a comparable grade to "The Chip Rack."

The description in "The Official" guide reads "for the worn condition on most of these." This would lower the value to the lesser of their grades or about 100.00.

I like and use both books but naturally, I like "The Chip Rack" best.
