you could certainly go the ebay way but it will take a lot of time and also the fees/returns, etc. will take time. My recommendations would be as follows:
1. As someone mentioned above, by a Red Book. It will give you lots of information about the different types of coins minted by the US.
2. Sort the coins by denomination, then within denomination by type.
3. Using the red book, determine which dates/mint marks are the key and/or semi-key dates. (They will be the expensive ones in almost all grades).
4. Search your coins for any of these key and/or semi-key dates. (someone mentioned the 1942/1 and 1942/1D Mercury dimes. The 1942/1 error is pretty obvious, but for the D mint mark the over date is not as obvious.)
5. Make a list of all of the key dates and semi-key dates you have.
6. Make a list of everything else.
7. It looks like you live in Alabama so see if you can find a coin dealer in your area. I'm sure the larger cities like Birmingham or Montgomery will have one.
8. Ask them to do an appraisal of your collection for insurance purposes. Tell them you don't want to sell, you just want an appraisal.
9. Decide if you want to sell or keep the collection.
10. If you decide to sell there are many avenues. eBay has been mentioned. Local coin shops are an option. There are also several large national dealers that will buy your collection or auction it for you. It comes down to whether you want the hassle of breaking it up into small lots to sell on eBay over an extended period of time. Or sell all or most of it at one time to a single dealer. The larger the collection you have the more they will be willing to pay on a per cent of value because they will make their money on volume.
11. If you decide to keep all or part of it, find a secure way to store it.
But above all else try to read and learn as much as you can about what you have and the potential value it may have so you don't get ripped off.
Finally make sure you are careful about who you let know about the collection and where it is stored. We don't want to read about your collection being stolen.
