What is the number one piece in your collection?
Is it a cool piece of memorabilia? A beautiful vintage card? Maybe it's a complete set from your birth year.
I don't know if I have something that fits that description.
I have this program, signed by a variety of Rangers and George W. Bush. I got him to sign while he was part of the ownership group so it pre-dates his run as Texas Governor and U.S. President. It's cool to have, but I don't know if I would call it the cornerstone of my collection.
At one point I was a game used cap away from having a complete game worn uniform of Rusty Greer. I had the jersey, the pants and the cleats. My goal was to put it on a mannequin in my man-cave. I ended up selling those items before I could complete the set. Or get a man-cave.
That leaves me with...well, with nothing to really call the cornerstone of my collection.
How about you....?
