The Facts About Numismatic Conservation Services
Back to the Coin News Index
Numismatic Conservation Services (NCS)
has been in business for more than one year, but is not the first
conservation service available to the numismatic community.
The American Numismatic Association offered conservation as one of its
member services. This service was discontinued in March of 2002 when the
ANA named NCS as their official conservation service.
NCS is based in Sarasota, Florida where it operates a state of the art
laboratory and employs experts in the fields of conservation and
numismatics. Unlike other conservation services, NCS specializes in
numismatic material. Collectors and dealers can submit all raw or
certified coins, tokens and medals for evaluation and conservation.
NCS procedures remove foreign materials, toning (tarnish), residues and
contaminants from the surfaces of coins, using a variety of non-abrasive
chemical rinses, depending on the particular situation, while protecting
the originality of the coin's surfaces.
NCS is NOT a coin "cleaning", "doctoring", "curating",
or "restoration" service. NCS only conserves coins that it
believes could benefit from conservation procedures. NCS DOES NOT
re-engrave detail, re-color, artificially tone, fill contact marks,
conceal hairlines, abrasively clean or participate in any other deceptive
NCS is not an "UP-GRADE" service. Frequently, a coin's eye
appeal will improve and in some cases the coin may grade higher, but this
is not the basis of the service. Any submission that is received with
requests "to conserve the coin so it will grader higher" is
immediately rejected by NCS.
The fee schedule for NCS is calculated based on the value of the
item(s) and amount of work completed.
When coins are received they are evaluated. The evaluation team
carefully examines the coins to determine what if any procedure is
necessary. Evaluations are charged at 1% of declared value with a $5
If a procedure is prescribed, the coin then goes on to conservation.
Conservation is charged at a rate of 1.5% of declared value with a $5
If selected, the submitter has the option of having his/her coins
submitted directly to an NCS approved grading service for encapsulation
after conservation. Presently, NGC is the only approved grading service.
Certified coins will not be removed from their holder unless evaluators
feel the coins will at least maintain their current grade at NGC after
conservation has been completed. While most coins remain the same grade,
some may grade higher. However, when residues or toning are removed and
the coin's surfaces become more visible, there is a chance that a coin may
grade lower. NCS has developed techniques and expertise to avoid this, but
it can and does happen.
To protect the submitter against loss, NCS offers Grade Protection.
Grade Protection is available for an additional fee of 1% of declared
value with a $5 minimum. If Grade Protection is selected and a coin grades
lower at an NCS approved grading service, NCS will make up the difference
as a result of the lower grade.
