The look like the Count-rite chips that go into the Count-rite holder. The holder (rack) is brown bakelite. The chips are plastic. They show up on eBay from time to time; you have all probably seen them at one time or another. The rack has built into it a chip measuring ruler and a metal "knife" like a shoe horn that slices into the stack to dispense the correct number of chips.

Here are two in ebay now -- one is missing the knife-slicer.
