Thank you for releasing this information to the chip collecting public Michael. I will not price any Playboy backup chip in the 2001 version of "Black's Catalog" and will so note your caveat emptor warning.
Yes, I would like copies of your documentation. I feel so bad for those chippers who may have paid big money for these items (not from me... as I had none to sell, except for a half dozen olive bunny $2.50's ten years ago that I sold for less than $20@).
