It made perfect sense to me that there are CC chips for tables 1-6 that were never used. I'm not sure why the 3 knowns tables are 7, 8 and 9 anyway.

Since you live in an area of the country where USPC chips were made, I was more than willing to believe such a find. Now if you photoshoped some first edition Flamingos, DIs, Saharas, etc, I am quite sure that your phone would have rung off the hook.
