Ah, nostalgia – the original iPhones were released when life was simpler, tech was exciting (and not ruining the planet), and everything was just a bit more fun.

That may be why a 15-year-old iPhone sold for a whopping $39,000 – more than 50 times its original purchase price.

LCG Auctions sold the first edition, an 8GB smartphone, on Sunday. It originally retailed for $599 in 2007 (which is $852 when adjusted for today’s inflation), and the price climbed quickly from an opening bid of $2,500 to over $39,000.

LCG Auctions founder Mark Montero said, “We expected the bidding for this item to be fervent, and it did not disappoint as a handful of avid and sophisticated collectors drove the price from just over $10,000 on Sunday afternoon to this record-setting amount by Sunday night.”

He added, “We congratulate the winners, our consignors, and all of the bidders for making this one of the most active auctions in our history.”
