How do I find the value of several old rifles and how would I sell them?

I have several rifles that were left to me that are about 30 years old or better. Some have extensive rusting due to being left in an attic and need some work. Where can I find out how much they are worth, if anything, and where can I sell them if they are worth something? Thanks

hello,,give us a list of what ya have and i'll see if i can help ya ,,please look on the guns ,,for a model number or name and a caliber if possible ,,then sometimes a serial number may help with dating them,,try to give as much details as possibly and pics would be great to determine the actual condition ,,once i see what ya got i may be able to steer ya in the direction for selling
