While it would be unethical for me to post private information in a public forum, these chips appear to be purchased by a University Professor for research regarding the slab controversy.

He only bought from me one cheap group of 5 chips that included a Chipco Slabfree Pledge chip, and wrote me the following email .....

"I was also wondering if you have any inexpensive slabbed chips for sale. The
reason I ask is that I teach a couple of numismatics courses at UT-Austin and
would like to have some for the students to handle (because of the controversy
about slabbing chips . . . I had Mike Skelton as a speaker earlier this year)."

I of course told him no that I had never handled any such chips, but perhaps this will allay any fears you may have about him.
