How can you tell if your bike is a classic worth money or just an old classic? I have found a couple of bikes at my Grandpa's house that look to be eather worth something or just a pice of old crap. The internet is not helping me much. The better looking bike is not very used. It has a AMF decal and is made in England.
Should i sell them for $15 or clean them up and sell them for more money?
