A Massachusetts man who paid $92,000 for a baseball card said the object is an investment for his son's future medical costs.
The card, which may be the last of its kind, was found by an antiques picker in Baileyville, Maine, last year.
LeBlanc said the card is an investment for his 4-year-old son, Alex, whose health problems require frequent hospital stays. The boy's mother died after giving birth, LeBlanc said.
"Alex is everything to me, and this is something I hope pays off," the father said.
