You have no link to the auction, but if one of them is the Jimmy Hendrix that I have seen offered before, I know where there are 2 others.

It is possible for there to be only one but not likely.
Chipco errors always come in sets of 2,4,6, etc. But it is possible that quality control would catch all but 1.
I have never been to Paul-Son plant in Mexico so not sure how chips are run down there.
