Shares were later sold for up to $275,000 after his first few crops hit the track, he stood for as much as $25,000.Polish Numbers is represented by 35 stakes winners and the earners of $20 million. He topped Maryland's sire list by progeny earnings in 1998, was second the next two years, and fourth in 2001. This year, he ranks fourth, with the earners of $3.2 million.Bred by Phipps, Polish Numbers raced for his breeder's son, Ogden Mills "Dinny" Phipps, and was stakes-placed at two and a track-record setter at Belmont Park the following year. He won four of 11 starts and earned $80,493. Two of his half-siblings, Private Account and Dance Number, were grade I winners.Polish Numbers covered 53 mares this year at Northview, which is owned by Allaire du Pont, Dr. Tom Bowman, and Richard Golden.
