Every bow is worth something. Some more than others. THe value of a used bow is whatever someone will pay for it. No more no less. The best I can offer is to keep an eye on eBAY and see what semilar bows sell for. That seriel number makes me think it is a '50's bow. Certainly there are collectors that will be interested in it. Personally, I prefer the bows from the '60's, but there are many colelctors that love what I call the vintage years.
If it is a good solid shooter, I have my thoughts on what it is worth, however, TRAD GANGS policy is to not quote appraisales on the forum. (see 4nolz) message at the begining of this forum. Now, since I do not consider myself as qualified to make an appraisal. I will not e-mail you my thoughts, but there are others here that are qualified. In any case, enjoy it for what it is.
