You know I had to say something........
I try for short, and to the point, but it often fails.
First, by definition, professionals are not necessarily experts.
Anyone can be a professional. Experts are those that are highly knowledgeable in a certain field. Some experts are not "professionals". Most professionals are not "experts." It's a greed thing.
Next, the crossover thing. I look at coins that are, what they are, and then say......."what if?"
Well, most of you know I sacrificed a PF70 set for crossover to PCGS about 9 months ago. All came back as PF69. The moral of the story?
LET SLEEPING DOGS LIE!
Most crossover deals wind up like folding with four aces in 5-card stud. You have coins that are yours. Why would you pay to have them degraded? I can send all my "W" quarters in and get them relabeled. Shoot, I can get them reholdered at the same time too. Six digit labels in a new style holder? All it takes is money. I think we used to get things chromed back in the 60's.
Looked great, but didn't run any better.
That's my humble opinion.
Have a great day and a safe weekend!
