Sick and tired of "shady" dealers...

How many times has this happened to you? or how many times have you heard of this happening to others? A dealer tries to sell a coin he or she claims is mint state when at best it's an au53 and then that same coin is offered to anouther dealer and they only want to pay ef45. This happens alot. I do beleive that a person just coming into our fine hobby cant help but get a "bad taste" and may say "screw coin collecting". I just received my latest issue of Coin World today and the only two articles on the front page display this exact problem. First a woman who was left several coins, not a hoard mind you, but a few silver dollars, some foreign coins and a silver half dollar. She then takes them to a local dealer and they offer her $100 for everything. They dont tell her that the "half" is an over date, one of less than ten in "captivity". Now I dont claim that the dealer should have been a "Capped Bust Half" expert but even the dummy I am, I can plainly see the "4" under the "7" and I'm blind in one eye and cant see out of the other one. Now if you ask me, I think they knew exactly what she had. This really "Stinks". Well after I got over this one, the next article talks about a man who goes several places with four $5 gold half eagles and everyone wants to give him $200 each. And what are they? They are mint state, just shy of "gem" with a "C" on the back. 1852 C that NGC graded two at 63 and two at 64. Can anyone look me in the eye and tell me a dealer cant tell mint state from bullion gold and exactly how many mints were around in 1852? Counting the 1850 D this dealer wanted to give this man $1000 dollars for 5 gold coins from a couple of the "rarest" mints around. With less than 20 of these 52's around in mint state not to mention the AU Ga. mint marked $5 this guy should have just "dropped his drawers" and backed into this "crooks" I mean dealers place of business. I am convinced that this happens "alot" and it's about time the people trying to pull this "" are exposed. I think next time I am going to let people know exactly how I feel! Any comments out there?
