1959 J. C. Higgins? Help?
 

Gang,
I stumbled onto an old bike at an estate sale. I paid $50 for it... it was quite rusty, and in rough shape. Looking for a hobby, I decided to attempt to restore it. It was a fun project, but I'm now wondering if I made a mistake by working on it (as far as value is concerned?) Any thoughts?

Also, I have attempted researching the model year, but cannot nail it down. Can anyone tell by simply looking at it, or do you need a serial number? Here's a picture after restoration.

Thanks for any inf. :)
