The violin is missing a tuning peg.
It was made in a workshop in Germany at the turn of the 20th century.Factories in Markneukirchen, Mittenwald and Klingenthal, among other towns, made thousands of these violins for export. They are still considered to be good student instruments today (not for concert performers).
If the violin is in good condition with very good tone, its current retail (replacement or insurance) value is approximately $800. If you were to sell it, you could expect to get the fair market (private sale or auction) value of approximately 40% of the retail amount, or $320, depending on location and actual condition. The bow and the case are usually included with the violin and, unless they ae something very special, do not affect the value.
