As long as there is a dark cloud hanging over that coin there will be no certification WITH A MONEY BACK GUARANTEE issued for it by any of the major grading companies.

Anybody can believe what they want about it. Personally, I believe Hoffman made it. I've seen his work and it was amazing what he was doing almost 40 years ago!

Hoffman did a lot of damage.
