Jeff Garrett: Only one example of this issue is known to exist. It first surfaced at the 1984 ANA Convention, and was purchased by me from San Francisco area coin dealer, David Stagg. The coin is deeply mirrored and unhesitatingly a true Proof. As mentioned earlier, the San Francisco Mint created special coins in the Proof format for this year. I sold the coin in 1984 for about $75,000. The coin sold two years ago for over $1,300,000. Not my best long term coin decision!
