The value of a violin in very poor condition, even if it were an authentic Stradivarius, would depend on several factors such as the extent of the damage, the quality of the materials used, and the craftsmanship of the instrument. Without examining the violin in person, it is difficult to provide an accurate estimate of its value.
It's important to note that violins labeled "Stradivarius Made Germany" are not genuine Stradivari instruments and their value is primarily sentimental rather than monetary.
