The items are counted by casino. If an item is used in ore than one casino, then it is counted twice, but has the same CHipGuide#. You also have to consider that we occasionally delete items when we determine that it is a duplicate. We don't always fill in the #'s right away after delete something. The ChipGuide# is not an accurate indicator of the # of items on the ChipGuide. Right now there are 244,947 ChipGuide#'s in use.
