Make sure you are comparing apples to apples when you compare his coins to yours. If you have a 1909 VDB penny in an exceptionally nice condition, say MS-63, it should be worth about $30 ( Red Book value). If the coin dealer is selling a 1909-S VDB penny in "fine" (F-12) condition it will look MUCH worse than your coin, but is worth nearly $1000.
There are two primary features of a coin that determine its value, condition and rarity. Chances are the high priced, low condition coins were rarer than the less expensive but nicer looking coins.
It wouldn't hurt to have him take a look at your coins. If he is a decent guy it won't matter if you buy something from him then or not. He can probably tell you are new to the hobby and may want to help you out. Of course, he probably hopes that his good customer service will make you more likely to shop there, but don't buy something for the sole purpose of having him grade the coins.
That being said... if he offers to buy some of your coins after grading them don't do it then and there. Some unscrupulous dealers will take advantage of unknowing person with a valuable coin by lying about its worth. They might say you have a coin worth $100 and offer you $80 for it. That would be a good price, unless the coin was really worth $500. I'm not saying he will be dishonest, just that you need to independently verify any offer he might make as reasonable.
