Those are definately Chipcos - The "CI" is a kind of mint or makers mark required on all casino chips - Chipco International (CI) out of Raymond, Maine puts it on all their chips.
They are probably someone's custom order from Chipco. You could not exactly duplicate them but you could get your own similar set.
You could try one of the other ceramic manufacturs - Nevada Jack, BR Pro's, Casino Tech's to create your own similar ceramic chips as well.
All of those chips have been reviewed and compared to each other and Chipcos.

They're pretty nice looking chips. Good luck.
