"So it would seem reasonable to assume at least one sheet worth of chips have this error."

If I am not mistaken, Paul-Son chips are run in sets of 64. If so there would be 64 of them. Quality control might or might not catch some or all.

When you find a Chipco error, you can bet there are 2, or 4, or 6, etc. Again quality control will catch some and destroy them.

BTW, I usually place a $100 value on error chips when I enter them in my program. I usually get them in the $20 to $50 range. I would have to see Jim's chip and compare it with a regular one before I would put it in the error catagory.
