During the Mansun Convention at The Live Room in Chester, fans will have the opportunity to bid for many of the bands rare items.
During this great celebration, there will also be live music by tribute bands, and a question and answer session with special guest appearances.
Andy Lyth, Mansun Convention Coordinator says: "Like many families mine was recently affected by cancer.
"I was moved by the support CLIC Sargent gives to children with cancer and I'm proud to be able to help by donating the auction proceeds to this very worthy cause."
