The Internet auction house eBay Inc. reversed itself Tuesday and is allowing bids for half of a 10-year-old grilled cheese sandwich that its owner says bears the image of the Virgin Mary. Diana Duyser, of Hollywood, put the sandwich up for sale last week, drawing bids as high as $22,000 before eBay pulled the item Sunday night. The page was viewed almost 100,000 times before being taken down. An e-mail Duyser received from eBay said the sandwich broke its policy, which "does not allow listings that are intended as jokes.''But Duyser, a work-from-home jewelry designer who has bought and sold items on eBay for two years, said the grilled cheese isn't a joke.EBay spokesman Hani Durzy said that the listing was mistakenly pulled the first time because it was deemed questionable whether Duyser could deliver the product."After looking at it a second time, there's nothing to indicate that the seller isn't willing to give up this cheese sandwich to the highest bidder,'' he said. "We're going to allow it to stay up.''The auction was back on Tuesday afternoon with a top bid of $11,000. The winning bidder also has to pay $9.95 for shipping. In mocking response, two similar items were later posted _ grilled cheese sandwiches said to be bearing the images of the Virgin Mary's used gum and Mary Kate and Ashley Olsen.
