His next race came in October, where he beat five rivals (including Lord Bolingbroke's 4/5 favourite Sejanus) to win another sweepstakes of 200 guineas each.

Goldfinder won this race and then beat Jethro again to win a Subscription of 50 guineas each a few days later.

In October he won the Newmarket Challenge Cup and Whip for a second time, in another walkover.

It was intended that he would run in a King's Plate against the undefeated Eclipse, but the day after the Cup he broke down in an exercise.

[3] After the death of Sir Charles Sedley in 1778, Goldfinder was sold for 350 guineas and moved to Mitcham, Surrey.
