My violin says it is a karl hofner violin made in 1959 in bubenreuth germany. Just curious as to the quality of it. I've had it since August and it has already cracked twice at the same time. Heres a link to some pictures of it since I dont knowhow to upload it directly to here:

Like many violin companies Hofner produced a wide range of violins from student quality up to professional. They also sell "white" violins nowadays like many other companies do, although I doubt that happened back in 1959. Depending on what you have it might probably range from not valuable to a bit valuable.
What I would find concerning is that you say it's cracked twice. I'm wondering why and where it has cracked. If it is around the sound post, that could be rather bad, I would think.
With regard to the intrinsic (as opposed to collector) value of stringed instruments in general, however, last weekend I asked my grandson's viola instructor (a Ukrainian gentleman who was formerly the principle violist in the Odessa Symphony Orchestra and still plays concerts) about his opinion on this and that brand of viola. He said that the name of the company and country of origin and even the price of a contemporary viola has little bearing on the best choice of instruments. That an instrument should be picked purely on this basis of its individual sound quality, its playability and lastly its appearance, without regard to who made it or where it was made. He pointed out that all current companies are capable of producing some wonderful instruments and some truly horrible instruments all under the same label. Just something to think about when asking, "What do you think about an instrument made by brand X?"
A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort. ~Herm Albright
