TPG's + TruView + E-Bay have dealers by the short hairs now. It will be great to be rid of them & bullion pushers. Agree that knowing your coin is the best way to go. I look for grading "mistakes" in only 3 years of the saint series, so my focus is very narrow. TPS's do make mistakes and a dealer's focus is often too wide to catch it. Beware though, a dealer will happily let you "free-grade" his table. As a collecter, I'll resell a coin to break even in order to get one I like more. Profit isn't my motive.
