One case of hobby here with good/great results- 2 cards. one large lot and one master set got me back $360 and with my other sales I am alreay in the plus colume.
I sort by 50's and the wife is of great help. I list hits immediately on ebay for 1 day auctions and then the follow up stuff for 3 day actions. On the following Sunday I take relist all unsold auctions after making market corrections for price. I hold a couple of sets back and sell the in 30 day auctions.
