Question about an E-500

My grandpa has been giving me a ton of his stuff and this time it was an Olympus E-500 with a 14-45mm lens on it and an extra40-150mm lens but both batteries he had for it have been sitting for idk how long so I’m sure they’re useless. Anyways what would the value of one of these be with just the camera itself and the 2 lenses?
