I've got a Raleigh Super Record that I picked up for $10 at a yard sale. Its a smaller frame, 52 or maybe even 50. It's in really good shape, looks like it sat in a garage most of its life. It has Suntour components and the frame says it's made in Japan. The vintage looks to be early to mid 80's. I can't seem to find any kind of price guide to find out what it's worth. Any help?
