Dan Serafini on baseball cards

Dan Serafini pitched for the Twins, Cubs, Padres, Pirates, Reds and Rockies from 1996 to 2007. His best season was 1998, when he went 7-4 for Minnesota. Now the owner of the Throw Like a Pro Baseball Academy in Sparks, NV, he kindly answered my questions about baseball cards.

"Baseball cards are great. I wish I did start collecting them when I was a kid. My silliest story is: the fact I didn't know that much about collecting baseball cards. I used to pitch with Sandy Koufax's rookie card in my hat in high school! Little did I know it would be worth what it is today. So I have a nice beat up Koufax card and a bunch of my own from all the different leagues and countries I have played in."

Thanks!
