I have the only KK chip I know of in chippers hands and it is slightly notched. I have the whole 11 chip set notched and the 10 un-notched released set.
There was a framed notched set given to all on the chips.
KK kept all his. Several of us wrote letters to him offering donations to his favorite charity but to no avail. The chips were sent to his LA offices and not to the MGM.
