Boxing Memorabilia : What kind of price would you pay for this ?

I have been offered a beautiful piece of Boxing memorabilia, it is a glove that is beautifully boxed and framed, it has about 30 signatures on it including over 20 World champs including such greats who have sadly ped away such as Willie Pep, Floyd Patterson and Archie Moore it and also other greats such as Hagler, Frazier, Arguello, Canto, Ortiz, Griffith, Pryor and Trinidad it is apparently a piece from the boxing hall of fame and has the relevant certificates and photos, not sure what price i would put on this item though, i am looking for some estimates from my fellow boxing answerers if possible, thanks.
