The set of four medals, including the Military Medal and three standard First World War decorations, had been expected to fetch around £900, but they were snapped up by a Midlands medal dealer for almost treble that amount during an auction at Glendinings.
The military honours belonged to Able Seaman Herbert Oakley Wilkinson, who was born in Worksop on 29th February 1888 to dressmaker Martha Harriet Wilkinson.
He lived on Foley Place and worked as a wire worker before joining Hawke Battalion of the Royal Naval Volunteer Reserve on 8th September 1914.
"We were expecting the medals to do quite well. They are quite an unusual group of medals for someone in the Navy," said Glendinings expert John Millensted.
According to research into Herbert s naval feats, he was wounded on Boxing Day 1915 while serving in the Dardenelles and was returned to his battalion.
He became part of the British Expeditionary Forces in 1916 and was admitted to hospital in Etaples for treatment to a gun-shot wound.
He was wounded again in 1917 and admitted to the 2nd Western General Hospital in Manchester.
In that year, he was awarded a good conduct badge and later promoted to Leading Seaman but reverted to Able Seaman in January the following year.
It is believed his Military Medal was for action on 7th-8th October 1918 when he joined his battalion in the capture of Cambrai in France.
The battalion braved heavy enemy barrage, and as a result of the operation, Cambrai fell within 24 hours and with the fall of the city, the enemy s natural defence to the North was turned.
There were 18 casualties, 86 wounded and 10 reported missing.
Herbert was honourably discharged on 10th February 1919 but mystery surrounds what happened to him after the war?
Are you a relative of Herbert or did you know him?
