Musk's ex-girlfriend, Jennifer Gwynne dated the world's richest man when they were studying at the University of Pennsylvania. She is auctioning a cache of photos and other memorabilia on the Boston-based platform RR Auction.
There are a total of 18 candid photographs featuring the billionaire's college relationship days. In the pictures, it can be seen that Musk had given a handwritten birthday card and a gold necklace to his then-girlfriend.
On Sunday night, the handwritten birthday card with the sign "Love, Elon" was edging north of $10,000 with an impressive 23 bids, as per Bloomberg reports.
After the handwritten birthday card, the necklace attracted the next most interest which comes with an emerald from the Zambian mine owned by Musk's father Errol---a South African property developer.
The pictures include previous unseen snaps of a young Musk hanging out with friends in the dormitory, and cuddling with Gwynne.
The Independent as quoted by Bloomberg reported that Gwynne dated Musk for a period in 1994 and has decided to sell the items to raise money for her stepson's college tuition fees.
Several things linked to famous entrepreneurs have been sold on RR Auction's site. The company had also auctioned Steve Job's first Apple-1 prototype in August for nearly $680,000.
Musk's ex-girlfriend Gwynne, in an interview with Insider Edition, said that the future Tesla Inc boss was already envisioning electric cars while they were dating almost 30 years ago.
