Nine-year-old boy from Arizona sells rare baseball card for thousands of dollars

PHOENIX (NBC, KYMA) - A nine-year-old boy from Arizona sells a rare baseball card for thousands of dollars after a lucky pack pull.

Mason Deane, a proud Arizona Diamondbacks fan, and his dad, Bradley, stopped by DNA Cards shop almost every week.

"We have a little bit of everything for everyone: Football, basketball, baseball, soccer for the World Cup. We've got Pokemon, Star Wars, Disney, Marvel, Deadpool," said Adam, the shop's owner.

"It's something that it's fun to do with your son, you know, father and son...we have a little, we call it a trading business, and we just like, you know, buy and sell baseball cards," Bradley expressed.

"We normally just look around, and, like, if I feel lucky, we normally get a pack," Deane added.

One day in April, Deane was feeling extra lucky.

"He was, and to quote, 'lucky enough' for Tops Chrome Black, so we got him a box at the time," Bradley shared.

Little did Deane know, he was about to knock it out of the park.

"That release happened to be Murakami Samas first major league American card," Bradley explained.

It's the only card of its kind: A redemption card promising an autographed card from White Sox player Munetaka Murakami in the middle of a spectacular rookie season.

"I was like, 'This is crazy, so never heard of a card like that," Deane spoke.

So, they took an even bigger chance putting it up for auction.

"I was sweating bullets as a father. Like, is this the right thing? Is this the right thing? Oh my gosh, oh my gosh, oh my gosh. Is it gonna work?" Bradley wondered.

It did work. In the bottom of the ninth, the card sold for nearly $75,000.

"I was like, 'Oh, wow, that's a lot.' I was just surprised," Deane remarked.

"I think that might be the biggest card to sell in the history of the store. So it's pretty sick," Adam spoke.

Like any nine-year-old, Deane wanted to "buy more cards, and some of it I wanted to get V Bucks," but his dad has a different plan.

"If you can take the value of it as is, and put it towards the college fund, that's what we offer to do," Bradley said.

A big payday and an even bigger memory.

"That's probably the best card I'm gonna get," Deane said.

"It's just been a lot of fun, you know. It's a crazy, once in a lifetime event," Bradley added.
