Coin Care
■
Cleaning Your Coins
It is not recommended that you clean your coins at
all. Even rubbing a coin with a very soft cloth can
leave minute scratches on its surface. This will
adversely affect the collector's value of the coin.
To improve a coin's appearance it is sometimes
acceptable, in very rare cases, to gently swirl the
coin in a diluted solution of pure soap, rinse it
with distilled water, and then allow it to air dry.
Never use any type of commercial jewellery polish on
coins. These compounds contain abrasive grit that
will mar the coin's surface. 'Home remedies' such as
vinegar, lemon juice and tomato juice should also
not be used for cleaning coins. All of these
substances do more harm than good.
If you feel that you need to clean your coins, take
them to an authorised coin care specialist who can
do the cleaning for you.
■
Storing Your Coins
Careful storage is very important. To prevent
improper handling, the originating mint encapsulates
mint condition coins. Care must be taken to avoid
contamination of the coin if it is removed from the
capsule.
Apart from avoiding scratches, a damp environment
encourages verdigris (a green or greenish-blue
deposit called patina on copper, brass and bronze,
which is caused by atmospheric corrosion). Albums
with plastic pages divided into many small pouches
may retain moisture and are unsuitable, especially
for copper or bronze coins. Plastic often contains
PVC-softening agents. When exposed to heat and/or
humidity, PVC (poly vinyl chloride) releases a
chemical that can react with coins and tarnish them.
Store your coins in PVC-free plastic. These clear,
plastic pouches are ideal because your collection
can be viewed without removing the coins from their
protective enclosures. These pouches can easily be
compiled into a coin album with a ring binder.
Besides plastic pouches, there is the option of
manila coin envelopes made of very dry paper. The
advantage of using these is that you can identify
the enclosures on the envelopes. However, you have
to remove the coins from the envelopes to view them.
Traditionally, coins are housed in wooden showcase
cabinets. Several trays are inset with circular,
felt-lined trenches that hold the coins. At the base
of each trench is a smaller hole through which the
finger pushes the coin up from below.
If you decide to keep your collection in a cabinet,
make sure it is not constructed of resinous
softwoods, but rather of well-seasoned mahogany or
rosewood. Moisture, natural oils, or acids in
resinous woods can tarnish coins. Avoid oaks as
well, because reactive fumes are released by the
wood.
An additional precaution is to wrap your coins in
specially treated soft tissue paper to prevent
particles from landing on them. This also isolates
the metal from any harmful chemicals in the
atmosphere. Choose coin cabinets with doors that can
be securely locked. Wherever you choose to store
your collection, keep your coins out of direct
sunlight and away from moisture. These elements
speed up the natural process of decay and corrosion
on the surface of your coins.
A strong safe deposit box is probably one of the
best places to keep your coins. Remember to install
a dehumidifier, or bags of silica gels that you can
replace on a regular basis. Most collectors place
coins in albums or trays with written descriptions,
photos, grades, dates, place of purchase and value.
It is a good idea to keep a duplicate copy of such a
list in a safe place.
Finally, install a good home security system. Insure
your coin collection against theft, loss and
destruction. Insuring your coins is a wise
investment, considering the legacy you are
accumulating with your collection.
