However, true antique rocking horses range in value from $2,000 to $7,000, depending on the aforementioned traits. Also worth mentioning is the fact that many early American rocking horses were painted black with white rockers. Horses have been used for entertainment since they were first domesticated by Native Americans about 10,000 years ago. In Europe, Arabians were popular through the 16th century but were then replaced by other breeds including the Dutch horse and the French poney. In 1776, George Washington acquired 25 horses from his neighbor Thomas Jefferson to use as military chargers during the American Revolution. These horses were probably mixed-breed cavalry mounts known as "hackneys" or "dragoons." They were likely sold by their former owners and were therefore not priced highly. In the United States, the hobby horse market began to take off in the 1950s when local toy stores would sell refurbished vintage children's toys. In the 1980s, China entered the scene with low-quality knockoffs of traditional European children's toys such as rocking horses.
