A California man was shocked to learn recently that the baseball he bought for just $2 could be worth millions.

Dale Ball of Visalia said he was in Action Sports and Coin in Sparks, Nevada when he spotted a Babe Ruth baseball card with an $8 price tag on it. Dale ended up paying only $2 because the store happened to be having a sale on that particular day.

The owner of the store appeared to be clueless of the fact that the card might be an authentic Shotwell W-575-1 Babe Ruth card. This card is an extremely popular collector’s item, as there are thought to be only two in existence.

“I said, ‘why is it only $8,'” Dale recalled of his conversation with the shop owner. “He says, ‘I can’t find it anywhere in the magazines. I think it’s fake.'”

Dale spent the next few days researching the card on the internet before he finally found that it could be one of the rare cards printed by the Shotwell Company in 1921.

“We went at it for three days before we were able to track down that logo on the back of it,” he said. “And the logo from Shotwell is exactly that logo 100 percent with the dye mark and the watermark.”

Upon reaching this conclusion, Dale went to an antique expert in Beverly Hills to get a second opinion, and the expert agreed with him.

Before the card’s status as this rare collector’s item can be made official, however, it has to be authenticated and graded by the Beckett Company.

“They need to look at it and basically authenticate it,” Dale explained. “And that’s the only way it’s gonna be proven that card is real. It’s so rare and no one knows anything about it.”

Dale said that he’s willing to sell the card, should it indeed be the Shotwell W-575-1, but not for less than $2 million.

Dale explained, “The only way I would sell this card is for the bidding to start at $2 million because to me I found the Mona Lisa.”
