Keene, whose health was failing (he died in 1913), sold all his holdings in 1912 to Colonel Edward R. Bradley's Idle Hour Stock Farm in Lexington, Kentucky.

Some confusion occurred over this sale, and Bradley resold most of the lot, but one of those he kept was a very dark brown yearling he named Black Toney.

This meant that the almost black yearling with no white markings and a fine head and body was a member of the last crop bred by Keene from his famous Domino/Ben Brush cross.

Black Toney became a very successful breeding stallion, siring many of the horses for which the Idle Hour Stock Farm became famous.

Black Toney spent his whole stud career at Idle Hour, producing many fine broodmares as well as winners.
