Seabiscuit by Susie Morton from the Champion Thoroughbreds Collection by The Danbury Mint - Plate No. A5883.  It is in Excellent condition with no chips, cracks, marks to plates - very slight wear to the back (still has retail sticker)!  It was purchased from an estate sale, so I don't know the history on it.  It measures app. 8" in diameter.  I will be listing many other collector plates so keep checking my store!
