Led Zeppelin T-Shirt Nets Whole Lotta Loot — $10,000 — On eBay

A rare 1979 Led Zeppelin t-shirt that was used as a backstage pass for a concert the band played at Knebworth House in Hertfordshire, England, sold for a whopping $10,000 on eBay.

Kyle Ermatinger, who sold the shirt through his online store Stormcrow Vintage, was blown away by the final price the tee garnered on eBay. "When I got the sale notification, my jaw hit the floor," Ermatinger said in a press release. "Given this shirt may be one of the only ones in existence, the price tag is completely justifiable. It's a rock relic, beyond rare."

Ermatinger bought the shirt for $123 from the family who originally printed the 1979 tees. "At the time, I thought I may have overpaid, until I got back home, looked it up online and noticed it was ranked No. 1 as the rarest Zeppelin t-shirt," he recalls.

A representative from Defunkd.com, one of the largest online retailers of vintage t-shirts, insists that the Zep shirt sale is a record-breaker on eBay. "Other t-shirts have been priced higher on eBay, but never sold," said Defunkd.com's James Applegath. "We've documented eBay's highest-selling t-shirts on our blog for years and nothing has come close."

The unidentified buyer, who declined to comment on the purchase, is located in Australia.
