AdamI do what Barry does as well (i.e. list on B/S/T, then move to eBay whatever does not go).
I tend to do a 10 day listing, starting it on a Thursday night so it ends the following Sunday night. I wish eBay prices were not all over the board . . . but if you want to get rid of something in 7 or 10 days and are fine with it going for whatever market price will bring (I do 95% of my eBay auctions with a $0.01 start price and no reserve), it's still a good way to go.
When I started collecting T206s, I only gave myself one rule --- I can never own more than one of the same card (and I follow this rule with very, very limited exception). As such, whenever I upgrade, the lower grade card has to go!
