In the case that the instrument was authentic, a violin of these characteristics can surpass the value of 120,000 Euros, in the case of a Stradivarius instrument also costs 600,000 Euros, according to the state of conservation and origin.
While reading these lines, the possessor of an instrument of these characteristics feels invaded by a euphoria. But the other face of the currency is that the probability of finding a Stradivarius or a Niccolo Amati is really very low. Most probable it is than these people are possessing of an instrument that was a later copy, which became in Poland, Hungary, Czechoslovakia and Germany from the beginnings of 21st century.
Although these instruments do not reach values of 200,000 Euros, in the case that these copies were done well-known manufacturers and being an instrument of good musical quality, if they can obtain interesting values (on 1000 or 2000 Euros in some cases). The antiquity also is one of the important factors in the violins since like general rule; an older violin is generally more valuable that a more contemporary violin, as long as it is of the same manufacturer and in very good state of conservation.
Nevertheless, besides Antonio Stradivarius and Niccolo Amati (the two manufactures during last two centuries), exist more than 30 manufactures of violins whose instruments not only enjoy very good reputation in the world-wide market but they are manufacturing instruments whose values of market can surpass the 18,000 Euros easily.
If I were with one of these instruments first that would do, it would be to spend the money and to look for a skillful judicial value to me to obtain an authenticity certificate.
