I can't pronounce his blog name, but Mike from Sports Syzygy and I just completed a small trade to go along with a small purchase I made from him. First the purchase:
Mike was selling team sets of 2011 Topps Chrome at super cheap prices. I picked up this set of Royals for $2 shipped. I bought it for the Hosmer, which is now my 3rd such card.
And here was the trade. The Elite Gwynn (numbered to 10,000) and the Chrome Lee (numbered to 99) I knew about. He snuck in the other Gwynns. I'd never seen the "This Day in History" Tradition card, but I really like it.
