I buy game used balls at a lot of games to either collect or to give away depending on my mood or level of intoxication. I had purchased an opening day ball that was pitched by Max, in retrospect, I shouldn't have given that one away.... I had some other cool ones too that got handed out. I held on to my post season one and was really looking forward to buying a game used World Series ball. Apparently the Nats Authentics store does not get any of the World Series Balls and MLB owns them all. They go up for auction. The cheapest of which last I checked was $1,000.00. Had to pass on that.
