I stacked the blues and blacks 40 high. I did not see any spinners. At 40 high the stacks are pretty damn solid. As for the exact color of the blue chips. I have no idea. Sorry. Looks to be a "darker" blue possibly. They were part of a mixed set that I bought (and don't need).
You also mentioned "cross hatching". Sorry, not sure what that is. I took a few more pictures.
The chips could use to be oiled. Otherwise they appear to be in great condition.

The blue and black diamonds are sold pending payment.
These diamond chips used to be mine and I believe them to be made by paulson in the90s. I even had this verified by a paulson employee via email a few years ago. They feel just like old starburst chips and stack wonderfully. I think they are leaded, nice chips indeed. I just did not need them, but I still miss them. You will not be disappointed.
