A saddle jockey Red Pollard's used on the legendary Sea Biscuit in 1938 has sold at auction for $US104,260.

Horseshoes worn by Seabiscuit during his famous 1938 match race victory over Triple Crown winner War Admiral and his famed 1940 Santa Anita Handicap win fetched $US35,311.

The auctioneers said it is unclear in which races the Seabiscuit saddle was used by Pollard.

The complete 28-lot collection of Seabiscuit memorabilia brought nearly $US200,000, including $US9,478 for a program of the 1938 match race which took place at Pimlico in Maryland.
