College photos, memorabilia of Elon Musk auctioned for Sh20m

College sweethearts Elon Musk and Jennifer Gwynne at the University of Pennsylvania.

They split when Musk graduated, moved to California and said he couldn't talk on the phone because it seemed like a waste of time to him, Gwynne said.

"We broke up just before he started conquering the world," Gwynne said.

The gold necklace with a small green emerald that Musk gave to Gwynne in late 1994 as a birthday present sold for Sh6m ($51,000).

A photo of Musk and Gwynne posing with four other resident advisors before a school formal in 1995 sold for Sh5m ($42,000), the auction house said. The birthday card Musk signed to Gwynne, calling her "Boo-Boo," sold for nearly Sh2m ($17,000).

The 18 candid photos were sold individually. Some show Musk in North Providence, Rhode Island, where Gwynne is from. She now lives in South Carolina and told The Globe she plans to use some of the proceeds for her stepson's college education.

She and Musk have not kept in touch.
