E.S.
I'm certainly not an expert, but I did recently help my dad out by selling my grandma's collection on eBay. I didn't have much luck selling the pennies, nickels, dimes or quarters. The only coins that seemed valuable to people were American Eagle Silver Dollars (I got an average of $15 for each of these from the 90s) and coins that were special issue coins, like a coin issued for the Olympics or Constitution anniversary, etc. Also, they are much more valuable if they're in mint, uncirculated condition. It's time consuming, but what you might want to do is go onto eBay and search on your coins. The ones with lots of bid activity would be the ones to keep. With the rest, you could try taking them to a coin dealer. That's what we did with the rest of my grandma's collection and he just offered a lump sum for all of them (not sure what it was, but it wasn't much). Hope that helps a little!
