Mike D. has collected cards for over 35 years, since he bought his first pack of Topps at the corner store in 1987. His fandom,  collecting interests, and contributions to Cardlines center around baseball in general and the Baseball Hall of Fame specifically.

Mike's collecting focus is centered on graded cards, mostly rookie cards, of Hall of Famers and future Hall of Famers. Lately, he's been enjoying dabbling in graded minor league cards. A collector/investor with a "buy and hold" approach, Mike takes the long-term view with his collection.
