A coin or any other item is worth precisly what someone will pay for it, it matters not if that person is knowlagable in the given field. Graysheet/Redbook/Beckett etc are nothing more than Price Guides (the emphasis is on Guide) As for a knowlagable person not paying over the odds for a coin LOL then what if that coin is the one needed to compleat a run ? or a coin they have been after for a long time
Ebay weather we like it or not has changed the world of coin buying for good, and in the long run I belive the average dealer will have to adapt or go out of buisness, my reasoning for this is more people will begin to sell there unwanted coins on the bay in the knowlage that they might well get more than is offerd by a dealer.
How often do we see in regular coin auctions selling for well over estimate? well then they have reached there true value, the same can be said of the coins that do not sell, on that day they were over valued to that market.
