As someone who has recently taken up 18xx in addition to a long time poker addiction, I love this idea! I do have some opinions:- On the inlay, personally I think you absolutely nailed the design for the intended purpose, and I strongly prefer the gray as opposed to the color coordinated ones.- The 1 and the 5 share two similar colors. Since these are inspired by 18xx, it would be good to incorporate the tile colors into a common chip. Therefore, I would propose changing to brown & green edgespots for the 1.- While I do really like the red the way it is, I don't like using black in three consecutive denominations. I wonder how it would look if you changed it to yellow (for the other tile color not used above)? Or maybe even better, maybe just the yellow half moons with no middle colors? Sometimes less is more, and it will resemble the 18xx offboard locations.- The 20 I like as is, thought I might swap the edgespot pattern with the 1000. The colors are basic and that makes sense for the workhorse chip. I still personally prefer using 25s in 18xx, so I would add a 25 as Joepro suggested above.- The colors on the 100 are way too typical. I would like to see it with coordinated edgespots that keeps a darker theme for the whole chip, like a deep gold and a bronze? Not sure what your color options are.- For the 500, I would change the green to white. This would be another typical combo, but I feel it would flow well with my previous suggestions.- For the 1000, I'd switch the purple to the light green from the 500.- The 2000 is a completely unnecessary denomination when you already have 1000, but I guess users would generally choose one or the other. Anyway for the highest denom chip, I'd go back to the edgespot from the 1 chip, and I think it would work better with the edgespot colors from the Majestic set, or even with white instead of black, as the black and gray mimic the 20 too much.I think generally speaking, I agree with Bassofthe regarding the edgespots colors. Since board games are likely to require a smaller chip stack per player than poker at any given moment, it would be better to coordinate the edgespot colors within each chip as much as possible to be able to easily differentiate denominations with singleton chips and small stacks.*Edit* Here are the colors I am roughly thinking, though the edge spots aren't right in the tool I was using, would love to see them mocked up for real with your tool & inlay with the correct edgespots:
