A little late to the party.
Other than The Mick being the inspiration for my username (Well that and an episode of Seinfeld!), he's the centerpiece of my small collection.
The 1968 Topps Mantle was the first that I received. In desperate need of a new magnetic one touch holder! I had to get a procedure done when I was ten years old. My Father, who often told me stories of Mantle, from his youth, gifted me this after the surgery was completed and I was feeling better. It started me on the long journey that I am still on today.
One of my other favorite Mantles is this 1956 Topps Mantle. It was on my first trip to Cooperstown two years later, that a small show was going on from across the Hall of Fame. George Mollyn, a card dealer, who still operates in the PA area sold this to my Father and I. George spent a great deal of time, talking to me about the 1933 Goudey set, along with sharing some stories of collecting from his youth.
The third was a more recent addition, that happened during the pandemic. At the time I was unable to afford (and as of this moment, still unable to afford) The 1951 Bowman Rookie of The Mick. I stumbled upon the Berk Ross set by chance, and made a post on here. Chuck graciously sold me the Berk Ross Mantle, at a more than fair price. To this date it's been my biggest purchase on this forum and one that I'll never forget
