When an item in the ChipGuide does not have an image, it means that we know that the item exists but we don't have an image of it. There are several ways that we can know that the item exists, but typically it is from a Chip Order Card or observation of the item in use at a casino. Also, if there is a series of chips that we have images of, let's say a $1, a $5 and a $100 chip, we can reasonable assume that a there also was a $25 chip.
