1. Age
of the certificate.
The newer the certificate,
the better. The older the certificate, the
greater the likelihood that the instrument certified has
deteriorated since the document's date of issue. Terms used
in the certificate -- e.g., "authentic in all its
parts," "mint," "fine,"
"good," or "functional condition" -- may
no longer be accurate. They may describe an instrument which,
in reality, no longer exists -- an instrument whose real
identity has changed.
2. Wording
of the certificate.
Since it is a document, a certificate should be read with
special care. What the certificate says -- but especially
what it does not say
-- is of great importance.
3. Photos
attached to the certificate.
The more valuable the violin or bow, the greater the need for
attached photos which show critical details of the certified
object.
Advice to the buyer: A certificate of authenticity, for a
violin or a bow, is comparable to an identification card carried by an individual. It is not
a certification of the physical health of the instrument
(which may be "authentic" but unplayable). At
times, such a certificate identifies only a corpse.
Importantly, a certificate of authenticity does not set out a monetary valuation or
state a price.
