Ken Griffey 500th HR comemorative ball

On June 20, 2004 Ken Griffey Jr. joined the ranks of some of the greatest hitting his 500th HR in St. Louis on Father's Day with his dad in attendance. after the Reds retruned from the road trip GABP had a poster handout (I'm sure I have the poster somewhere) and for the first 500 to run to a stand a limited edition ball. I thought the ball was a handout to the first 500, until later I asked someone who had one. I went to every stand in the park and finally found one at the last stand to check and it was the last one! (I bought the last available ball in the park!)
