What is a copy of Antonius Stradivarius made in Germany year 1800 worth?

Answer 1

It seriously depends o who makes the copy, some copies are absolutely wonderfully done where others are horrible. If you go back to the first part of the 20th century, international copyrights were not well enforced. There are many "Stradivarius" violins from that time which are not even copies of a true Stradivarius, just ordinary violins with that tradename.

Answer 2

There were many violin makers and violin making shops in 19th century Germany. One must know the schools or regions in order to determine generalities, then be able to discern the individual traits of the makers to determine more specific things like market value. So called factory productions are the least valuable, coming in ready to play "kits" which were then exported as "student grade violins" to cities all over the world. Better quality instruments are made by one person and deemed to be "exact" copies of "famous" Italian instruments, such as the so called "Messiah" Stradivarius of 1716. These are sometimes fairly good sounding instruments which may range in value from several hundred dollars up to several thousand dollars, depending on the individual maker's reputation for overall quality which has been established over a long period of time. If an appraisal may be deemed necessary, then take the instrument (in question) to a violin shop in your area that is owned by a competent, honest, person.

Answer 3

The value is determined by the condition, quality of workmanship, wood selection and sound. Take it to a violin shop for an evaluation.
