Jim, you and everyone else should dissect an inlay chip. Take a cheap, worn, damaged inlay chip and either pry off the inlay with an exacto-type knife or hold the chip with two pair of pliers and bend/break the chip apart.

Michael, I know of hardly an exampe of errors in manufacture of embosssed and engraved clay chips. The only one I can readily find is the common Jockey-on-Horse chip pictured below. Most of the edge of the chip is perfect/regular, but at one section clay oozed out of the two halves of the mold and remained there. Both sides look the same -- the oozing clay is from the center of the end/edge of the chip.

The bottom two chips are "embossed"wood chips that have been mis-stamped.

The green chip is another messed-up inlay chip. The inlay is perfect on the reverse side, and is smooth/flush on the side you see.
