The fan who came up with Barry Bonds’ record-tying 755th home run ball is cashing in.

Adam Hughes, a 33-year-old plumber from La Jolla, Calif., said Friday that he was going to sell the souvenir through SCP Auctions.

The minimum bid price has not been determined. The same auction house sold Bonds’ 700th homer ball for $102,000 in 2005.

Hughes got the ball in the left-center field seats last Saturday at Petco Park in San Diego. Bonds’ homer tied Hank Aaron’s career mark.

“He made a lifetime achievement and I feel very fortunate that I caught this ball. Never in a million years did I expect it,” Hughes said in a statement released by the auction house.

SCP, which is a partner of Sotheby’s and specializes in high-end sports items, said the ball would be available in an online auction Aug. 28-Sept. 14.

Three days after tying the record, Bonds hit home run No. 756 to top Aaron.

Matt Murphy, the 21-year-old New Yorker who caught Bonds’ record-breaker in San Francisco, told NBC’s “Today Show” on Thursday that he was leaning toward keeping his prize, even though it could fetch around $500,000.

“It’s the greatest American sports accomplishment in history,” Murphy said.
