Err...I have a box full of Peter Warrick stuff. I'm not proud to say how much $ I've lost on him since it's depreciated so much, though. My favorite Warrick item is probably a game-used autographed shoe I bought...authenticated by ASI.
In terms of memorabilia, I like my Stephen Drew autographed baseball quite a bit, being a huge FSU fan. I want to get JD's and then display them together.
I have a bunch of this guy right now:
Bought another one of those x's (bottom one) lately, but didn't scan it yet. They're arguably my favorite, because they're a decent stack of cash. I have lots of interest in his progression, of course. Milledge's stuff was ice cold until around this summer...due to a rough start. His cards are beginning to heat back up again.
