I had 4 examples of the '1' in their original state of preservation which I sold for 600, 1000, 1700 and 3000. I am not aware of any other '1' chips undrilled... nor am I aware of a '5' chip.

Back then; USPC wrapped these chips in coated craft paper in the box.

Other than the box of 100 '50' chips found, one used example was found in AZ, years ago.
