Cheltenham Gold Cup is stolen from Mould.
But of more concern to Nigel Dimmer, whose family firm Martin & Co have been manufacturing a new Gold Cup every year since 1935, could be another piece taken from a break-in to Mould's home in Wormington near Broadway.
Gloucestershire police reported a Challenge Cup trophy and Britannia Handicap trophy to have been stolen from the prominent owner.
"I believe it is Raymond's Gold Cup that has been stolen. I think it's absolutely awful for something like that to happen to a lovely man who has done so much for National Hunt racing," said Dimmer, who was responsible for trophy presentations at Cheltenham for 45 years.
"There is a new Gold Cup made every year. It's terrible news, but the cup is replaceable.
"What I would be extremely concerned about, though, would be if the Grand Annual (Challenge Cup) Trophy, that he won this year, had been taken.
"It is a beautiful piece of silver, a one-off and part of Cheltenham's heritage. I would appeal for it to be returned."
