In NV the manfactures logo must be on the chip.
It is on all NV chips. It is either shown on the chip or it is there in UV.
If you use a house mold and do not want the H&C to show, the casino has to pay extra for the H&C in UV.

If I remember right UV costs 7 or 8¢ a chip.

If H&C is in UV the UV is shown on the art work sent for gaming approval.
