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.

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.
