If it's a specialist collection then it'd be helpful if you could say what it's a collection of - stamp collectors mostly do one or two particular things and know little about other areas. If it's not a specialist collection (as hinted at by "sent him stamps from all over") then I'm afraid it's fairly unlikely to contain much of interest, other than perhaps to kids (do kids still collect stamps?)
