Luke Nolen was speaking to the media after the race at Moonee Valley when the helmet complete with skull colours is believed to have to been taken from the mounting yard. His wife, Alicia Nolen, said Luke was "gutted" and "devastated" and urged the person with it to hand it back. A picture of a man, taken from security footage inside the mounting yard, was being circulated on Twitter this morning. Black Caviar chalks up another stunning victory "Such a low act after such a fantastic night," she tweeted. They have video footage of theft. Hand it in mate, no charges," she added. Ms Nolen said the helmet was going to be a souvenir for their children. Victoria Police, just after noon today, said it had yet to receive a report of stolen property from Moonee Valley racecourse. Allan Morrison, who owns Legends & Heroes Memorabilia Shop in Richmond, valued the helmet around $40,000. "If he's worn that helmet for all of his 21 wins on Black Caviar, I'd put a value of $40,000 - but there could be someone out there willing to pay $100,000 for it," he said this morning. There is a massive demand for Black Caviar memorabilia and the helmet would be a real collector's item. But it is not going to be more valuable to anyone than Luke Nolen himself. He said news of the alleged theft was quickly spreading "He wouldn't be able to offload to a sporting memorabilia shop," Mr Morrison said. We'd be on the phone to police before he could step both feet in the doorway. I'd imagine he is sitting at home right now feeling very lonely. If he was a smart man, he'd walk into a police station in the next few hours and own up to what he's done. If he is a crook, he might try and sell it on the black market, but 95 per cent of buyers would know it had been stolen and steer well clear. "I am sure Luke will get the helmet and colours back," he added.
