Hi, Mark,
I am in Photography business for 25 years. I took a great condition Rolleiflex 2.8 F, what we thought in the USA as 98% to Japan, a camera store I had known for 35 years.
2 guys sat down with white gloves with note pad and magnifyer(lupe), spent 10 to 15 minutes each gazing at, and took notes. Guess what, EX ++ in the USA 98 % became EX only 88%. Of course, if I had visited many other camera stores, I might get some better than others. I do not know about coin collectors, BUT if you touch it, more likely becomes MINT-, there will be invisible scratch on it by bear eyes!
At last, you 've got to see it to believe it!
KEN TODA, I can not turst anyone's rating till I see it. HIgh Point, NC
