Selling Race (A),
in which horses to be sold are run. These horses must have the sale price ticketed. The winner is generally sold by auction, and the owner gets both the selling price and the stakes. If at the auction a price is obtained above the ticketed price it is divided between the second-best horse and the race-fund. (See HANDICAP, SWEEPSTAKES, PLATE, WEIGHT-FOR-AGE RACE.)
The owner of any of the horses may claim any horse in a selling race at the price ticketed.
