I don't think a 1K chip was/is in the rack. Indiana casinos have orange $1000 chips (those that do have a $1K, not all do), and most of them are 8V on the IHC mold. I'm working on a suitable fantasy orange $1K for this set, that won't clash with the $500 (and won't have 8V spots, obv.). I like the Beltera $1000 chip colors, and may use it for inspiration with different spots.
I figure the quarter-pie could be a no-denom chip and serve as a 5c, $5000, or bounty chip, or even as a $2.50 chip, if somebody wanted to run a pink chip game (see my updated post before your purple chip post). Did you notice the oversize inlay on the $500?
And yeah, I'm not impressed at all with the original BC $5, and I think mine is tons better than theirs. But the $5 chip could be drastically improved by moving away from the original's colors (and maybe spot config, too). I do like your orange spot,.
