An 1889 Celtic winner's medal is up for auction at McTear's in Glasgow.
The rare piece of footballing history was awarded to James McLaughlin for his part in Celtic's victory in the Glasgow North-Eastern Cup.
McLaughlin played as keeper and full back for Celtic for two seasons.
He was on the pitch during the team's first game against longstanding rivals Rangers.
A strong player, he even turned down an offer to play for Arsenal.
McLaughlin passed the medal down to his grandson Bill, who explains: "One day he [McLaughlin] called me into his room where I found him and his eldest daughter Cis.
"He showed me the medal and said, 'This is for you but, until you are old enough to look after it, I am asking Cissie to take care of it for you'."
Bill went on to say he had discussed the sale with his family: "They love the stories behind the medal but when we talked about what should happen to it in the future we all felt that it would be entirely appropriate for it to be passed to a football fan who would treasure it."
It's valued at £10,000-20,000 ($12,986-25,973) ahead of the August 12 sale.
Football medals are popular with collectors, with Pele's 1958 World Cup winner's medal selling for £190,000 ($290,000) at Julien's Auctions earlier this year.
