Claim 10:
11. A method of operating a gaming table system comprising:
illuminating a light-diffusion box with diffused light, wherein the diffused light shines through a transparent portion on an underside of a chip tray that rests on a perimeter of the light-diffusion box and illuminates an edge of one or more chips in a chip stack visible via the transparent portion, wherein the illuminating is in response to detection of a bank-change event via analysis of a first image of gaming activity taken by a first image sensor at the gaming table,
capturing, via at least a second image sensor in response to illumination of the light-diffusion box, an image of the edge of the one or more chips;
associating, by an electronic processor in response to electronic analysis of the second image via a neural network model, a color pattern on the edge of the one or more chips with a denomination value for the chip stack;
determining a height of the chip stack; and
computing a monetary value of the chip stack based on the denomination value, the height of the chip stack, and a known edge thickness of one of the chips.
