Just now on eBay I found two more embarrassing “authentications” from PSA. Don Knotts was never within 1000 miles of these cards. Why anyone would pay their hard earned money to a company that has made countless mistakes in authentication...to authenticate their item...is beyond me. How many times does a company have to drop the ball before people say enough is enough?
I believe the Knotts cards are the product of a known ebay forgery mill seller. There are a few ebay "powerseller" types who buy this junk cheap, get it certed and then flip.
I have warned one such "powerseller" he was passing junk and he always ignores my messages. He doesn't give a damn... as long as something is certed he'll sell it. Sadly he is not alone in that philosophy.
Horrible that someone forges Knotts. The man was a great IP signer and I heard good TTM as well. There should be a wealth of real ones out there
ebay seller JMHAY05, now using the name OPM1877, was/is a major seller of signed TV show cards of this nature.
A seemingly limitless supply of cast signed items over the years. In my opinion, the space related items he has offered have all been suspect.
I'll let you be the judge of the material in question.
