Is it still grey sheets? Or something else now? Or combination? How influential (or relied upon) is the PCGS Rare Coin Market Report?
Most dealers know and always have known to ignore price guides. The Grey Sheet was the only exception. But now that the Grey Sheet has changed, I honestly don't know if they even use it anymore. But they can always access the electronic dealer markets and check prices that way. It's the most current and most accurate method there is - always has been.
I don't know how they arrive at their selling prices but when I offer items to them they whip out their Smart Phones and surf up some site (don't know which one).
Many still do especially smaller dealers. Sale prices have been becoming more popular but as of now Grey Sheet is still king for dealers
