I have some unusual poker chips on eBay, auction ending today (Tuesday) at about 11 PM (ET). I never saw chips like these before: regular embossed antique chips with a metal overlay on them! Below are pictures of how the chips look without the metal overlay, the same embossed chips with the metal overlay, and a chip I took apart to show the metal overlay.
