And Roger Aston has vowed to track down descendants of one of original owners and hand over his medal.
Mr Aston discovered the buried relics of the Great War among the potato patch at his home in Smethwick, West Midlands.
The 64-year-old found two medals buried in the soil – one British and one German – and decided to dig deeper.
Mr Aston discovered that one medal belonged to Private Francis Hubball, of the lst Battalion South Staffordshire Regiment, and compiled a brief personal history using genealogy websites and his local library.
He found out that Private Hubball died in Flanders, Belgium, on October 26 1917 – almost 96 years to the day before the medals were discovered.
Born around 1884, he married Agnes in 1907 and they had four children – Frances, Harold, Annie and Frank – who all lived together in Smethwick, where Agnes remained until her death in 1969.
Mr Aston said: “The main problem you get is the spelling of names. His last name has also been spelt Hubble in some documents which makes it difficult to track his relatives.
“I would love to be able to give the medals back to members of his family before next year’s centenary.”
