I just discovered the NGC price guide and really like it. You can also check the completed auctions section of ebay to use as a rough price guide.
I also view all of the other items a seller is selling.
I like to see that they are consistent in their offerings. If someone is selling a valuable coin along with a bunch of household knick-knacks it makes me suspicious. Or if they are selling raw coins that have a reputation for being faked, like Chinese Silver Dollars, USA Trade dollars, etc. . .
But if they seem to be a professional or amateur dealer with a niche that they specialize in, that makes me feel a lot better.
