Replying now while I see this, so I don't forget, -- I have a few racks of solid ASM (?) chips in the same square-in-circle mold in either a yellow/mustard or a lighter green shade, but they would need to be milled to put an inlay/denom on them, although I'd let them go for what I think would be a reasonable price.
If that sounds like something you might be interested in, let me know and I can take some photos alongside some Throne Room chips (I have a set of around 1500-1600+ of those myself, and might also consider selling a rack of certain denoms, if you're looking to add on.)
