The question concerns the white chip in the top row.

The yellow chip in the top row is from the Dallas AC. The bottom 4 chips are from the Denver AC (2 on the left are USPC, 2 on the right are Burt).

I was told the white chip in the top row is from the Denver AC. I immediately said Dallas AC. Now I'm not so sure. The white and yellow chips don't match. Unless I hear differently, both will be attributed to the Dallas AC. Can anyone verify my attribution?
