Does anyone know a good reference site for odd antique values, such as magazines, ornaments, dishes, etc.?

My 94 yr. old granny is a hoarder who's been living in the same house since 1941. We are currently moving her/cleaning out this home, and coming across some amazing finds--i.e. 1941 National Geographic/ 1952 Family Circle/1953 Field & Stream, vintage clothing, antique toys and furniture, as well as many odds & ends that we know nothing about (except that they're very old). It's not like we can rent a room to an Antiques Roadshow expert (lol), so any other ideas please?
