Wade Jones is a fan of Elvis Presley, but says he's not a fanatic. That's why - after a grilled cheese sandwich said to bear the image of the Virgin Mary sold on eBay for $28,000 US - he decided to sell three tablespoons of water from a cup that Jones said was used by Presley during a 1977 concert.

"It's one thing to be an Elvis fan, but then you tell them you have this cup of water and they think you're a fanatic," he said. "I'm not like the people bidding on this water."

The water fetched $455 US on Saturday at the online auction.

Jones was 13 when he watched Presley perform in February 1977 at the Charlotte Coliseum, now the Cricket Arena. He says he watched Elvis drink from the cup while he introduced the band.

After the show, Jones went to the stage to snag a souvenir - perhaps a scarf that Presley would throw to his audience. When police wouldn't give him one, he asked for the cup and water. He stored the cup in a deep freezer for eight years, then melted the ice and transferred the water to a glass vial.
