The sports memorabilia world is going crazy for Shohei Ohtani.

His autographed Topps rookie card sold for $6,725 on Monday night.

"It's a truly foreign market that is buying his memorabilia," said Rick Probstein, whose company sold the card on eBay. "Aaron Judge and some of the other baseball stars we have seen on the rise have been boosted by a U.S. market alone."

The red-ink autographed card, from the 2018 Topps Heritage set, could have been bought in the $1,500-to-$2,000 range toward the end of spring training.
