I would encourage you to either go with a hybrid chip, or with the diamond-molded ceramics, or simply remove the mold aspect completely.
^^ This, 100%. Hybrids are your best bet for image clarity for the inlay area, plus it drastically helps better achieve the faux-clay chip look (and feel) you want. Ditch the fake mold markings.
Personally, I'd make these minor color changes:
25 - swap out the olive green spot for a light yellow and a little more pizzazz.
100 - replace the gray/tan spot with light pink, again, more in line with the other (brighter) chips.
500 is okay, but I'd probably swap the lavender and purple -- lavender base, purple spot -- to get more contrast against the 100 chip.
That 8d18 white 1000 chip is stellar. Best chip in the entire thread so far.
5000 needs work, imo. I'm not a fan of the flower-pie pattern unless the base (flowers) match one of the spot colors. (The current dark base with dark inlay looks like a deformed turtle in a hex-pie chip). Might even consider just making it a hex-pie, period -- a unique pattern not available anywhere else.
EDIT/ADDED: looking at your inlay shapes, the 100, 500, and 1000 all mesh very well with the spot patterns. Along those same lines, you might consider moving the hex pattern to the
1000 5000, and making the 25 a tri-moon.
