Last month four police officers toured all 92 football clubs throughout England and Wales to collect signed football shirts to raise money for the Holly and Jessica fund, which was set up following the deaths of the 10-year-old friends.
Inspector Steve Selves and PC's Phil Enderby, Paul Roberts and Ifor Maddox spent four days on the road and now 72 signed football shirts and 13 signed footballs from Peterborough United to Manchester United will be auctioned off.
PC Paul Roberts said: "All the football clubs have been extremely generous and we would like to thank everyone who supported us throughout the tour, however it is now the public's turn to help and get bidding for that rare football memorabilia.
"These are things that money can't normally buy - so here's your chance and you will be donating to a very important cause at the same time."
The auction, which is a partnership between Cambridgeshire Constabulary and e-bay.co.uk starts at midday on Friday 15th November with the hammer going down on Wednesday 11th December.
So if you're a football fanatic or looking for that extra special gift for a loved one - get bidding before they are going, going, gone!
