Jbmi, I don't know exactly what your Colt is worth. What I do know is, in the mid 60s I sold a 5-1/2" Colt SAA & have been sorry every since. I'd think long & hard before I sold that Colt. I'd take it out & use it. You will have a great time & as long as you don't abuse it, a little shooting & normal wear won't take much away from it's value unless it's really hot collectable. I'd enjoy it.
