My family is planning on getting rid of some of my dads old bikes that he had collected and were wondering how we can find out what they are honestly worth. There are some pretty old bikes and a few might be worth something. We have a 1945 Roadmaster, some old Schwinns and Hiwathas. My dad loved these bikes but we cant keep them and don't want to get ripped off.

eBay, eBay, eBay. You'll get market value for them.
Otherwise, try a google search and see what comes up...but I don't see much value in the Roadmasters. Maybe the Schwinns depending on what, exactly, they are. Too many of them drops their value IMO.
The Hiawatha's seem to do better.
