Picture: Katrina Partridge Source: Herald Sun YOU'RE looking at the most expensive dam and foal package in Australian racing - champion broodmare Helsinge with her latest foal, a full sister to Black Caviar. Bloodstock agents estimate they're worth $8-12 million. On Tuesday, the foal's older half-brother set an Australian yearling record when he sold for $5 million. The sister to Black Caviar by Bel Esprit, if sold next year, could bring $4 million. But owner Rick Jamieson said she's not for sale. As for the $5 million sale, he said: "I couldn't describe the build-up. It was amazing. Jamieson is in discussions to take a share in the colt, which could be the last offspring he sells out of his 11-year-old dam. "I'll certainly be keeping all the fillies and I'd like to keep all future colts as well, but you'd never say never," he said. Jamieson sold Black Caviar for $210,000 as a yearling, but after her exploits the foals have become valuable commodities. Two years ago, All Too Hard was sold as a yearling for $1.025 million and was recently syndicated for $20 million. Last year, Helsinge's Redoute's Choice filly sold for $2.6 million. Helsinge is in foal to Casino Prince, which will make her next foal a full brother to champion three-year-old colt All Too Hard.
