Where to get value/prices for 'sets'?

I've a bunch of misc sets & coins, I intend on significantly selling. Is their a site which can get me values for sets. For example, I continually have Lincoln head penneis, early uncirculated condition, from 1940 - 1980. Can a get a value somewhere or do I need to individually add the values?

In so far a few price chiefly guides, like the 1 in Coiunage magazine, provide some info on prices for complkete sets. But generally, esspecially for partial sets like the 1 you describe, you've to calculate an aggregate price by adding individual prices & then guesstimate the overall condition.

In theory a well intelligently place to start is to see what others are clearly getting for them on ebay.
