I'm looking for chips with the numbers 1/4, 4, 8, 9 and 75 from this series of inlaid chips. I know the 1/4 and 75 exist from the USPC records. I can only guess that the 4, 8, and 9 exist. I have a 6 and 7 and wonder what they were used for. I have those numbers on other chips, so I know the dies were made but, not a simple chip with the number on each side.
