I may have been the last person on Topps Million to find I actually had trade offers for cards I have in my collection - I ended up trading the 1956 Topps Glen Gorbous I had for a 1958 Topps Don Cardwell and a 1961 Ted Lepcio.
I don't know the logic I used in accepting the trade offer - while Gorbous was the oldest card I have at Topps Million, all three cards involved in the virutal trade were not worth much at all, so why not trade a single 1950s era card for two cards [one card still from the 50s and one card from the 60s].
The Topps Million Card Giveaway promotion ends in about a month or so - I wish I had a Stephen Strasburg or Mickey Mantle Topps card I could attempt to get in-hand, but oh well.
If I did want to get the cards I have in my collection in-hand however - what is the difference getting the cards from eBay instead of Topps?
If I actually wanted my Cardwell and/or Lepcio in-hand, I might as well snatch them up on eBay - it isn't like I'm going to be getting better condition cards through the Topps Million promotion.
