The Jockey Club Plate, not to be confused with the Newmarket Town Plate which was first run on the Round Course in 1666, was restricted to Jockey Club Members and run at Newmarket annually. The earliest record of a Jockey Club Plate was in 1753 when two were staged two days apart. The first, for 4-year-olds, was run on the Round Course on Tuesday 15th May 1753 and won by Beau Clincher owned by Lord Gower, while 2 days later a second subscription Plate for 100 Guineas was contested on Thursday 17th May 1753 and was won by Crab owned by Captain Vernon. The races provide vital evidence confirming membership of the Jockey Club.
