As I say, I have no axe to grind here but likewise, I speak as I find from personal experience. If a willing seller sells to a dealer and then that dealer finds a willing buyer for the same coin then that's fair trade in my book. Seller, dealer and buyer are all happy. Grading is always subjective and anyone buying should form their own opinion, whether or not the dealer has suggested a grade or otherwise. I can't see why you would assume a money back offer is "hush money". Again, only my opinion.
