Obviously, from chips such as that Caesars AC hologram, we know they had a mold with recessed center that would take an inlay although it was rarely used.
We also know that in a couple of cases, a highly polished chip was supplied to casinos (Monte Carlo roulettes spring to mind).

Now look at this one below. Hard to see from the scan I know but it has a recessed center (you should be able to see the circle cutting through the denoms) but very very shallow (not sufficient for any type of inlay). The dyesub design is printed on both levels in one. BUT, the 'inlay' area is highly polished and the rest of the chip is standard 'satin' finish.

This particular design seems to be semi-generic - apparently sold as a home poker design originally, but slight variations (casino name etc.) were used for other orders, particularly to the far east. So I have many to compare it with but all the issued ones appear to be regular style. This is the only one I found like this. (and this one also has a rough unfinished edge)
