Looking for info about my Ruger old style single six convertible?

My dad gave me his Ruger single six .22 convertible revolver. I don't know much about the gun except that he bought it in the mid 60's for $50. It's the first gun I ever shot and I don't want to sell it but I am interested in finding out when it was made, what it's worth and if the value would change if I re-blued it (it's pretty worn from being in a holster) and replaced the grips (the left side has a chunk of wood missing), The serial number starts with 463 and I would appreciate any info you could give me. I have both the standard and the magnum cylinders. Thanks so much, Debs
