It would be about $150,000, according to the latest auction figures.
This is an average of all auction estimates published so far this year, according a spokesman for the American Association of Zoos and Aquariums.
The figures include estimates of value from previous auctions, but they don’t include a number that would be set by auctioneer Craig Anderson, who sells the horse to the highest bidder.
Anderson said last month that he expects to sell about 300 horses for his annual $15 million sale, which will begin at 5 p.m.
ET Tuesday at the New York Hilton Midtown.
The auction will be the largest single-day auction in the history of the sport, which typically draws more than 2 million people a year.
In the past, the most famous horse auction in history was the 2012 auction of the American Red Cross.
