Best way to sell MTG cards?

I played Magic the Gathering from 1997-2003 and I have a large collection of well kept mint cards that are just taking up space in my closet (some cards at the time were extrememly rare and worth 5-50 dollars per card - I don't know what it's worth now). I entertained the idea of putting up the rares as single auctions on an auction site like eBay, but that require so much time and effort to ship all of these. Is thier any easier way to do this? If not, how do I price cards for single auctions that have been out of print for almost a decade now. I have a hard time determining things like 3th, 4th, 5th edition so I want to do this the right way to maximize the money. Thanks to anyone who answers.
