T-206 on eBay

One of the most popular vintage card set, the T-206 has hit eBay this past weekend. Two cards from the set, A Ty Cobb(5 EX Grade) and an Izzy Hoffman(8 NM-MNT Grade) are being auctioned off separately . Six days are left to bid and the Ty Cobb card has reached over $1,500; the Izzy Hoffman $250. I can't imagine what the final price on the Ty Cobb card will be. I'll post a update when it's over.

Questions for you readers.

Have Collectors & Sellers ditched auction houses for eBay?

Do they make more of profit on eBay or at other places.
