Handling Your Collection.

When it comes to collectable coins, the less they get
handled, the better. They’re best kept in a coin
holder, with as little contact as possible. The better
the quality of the coins, the more important it is to
handle them properly.

If you have to handle them, it’s best to hold the
coins on their edges. The less contact with your skin,
the better. Fingerprints will quickly lower the value
of uncirculated coins.

You also need to keep the coins away from your mouth.
The moisture from your breath can eventually cause
spots on the coin. Some collectors and dealers wear
gloves and masks when handling coins.

If you need to place your coins on a surface, a clean,
soft velvet cloth or pad is best. Don’t drag the coins
across any surface. Scratches will greatly reduce the
value.

Cleaning is another easy way to reduce the value of a
coin, sometimes by as much as half. A shinny coin is
only good when it’s the original shine. If a cleaning
is absolutely necessary, the services of a
professionally is strongly recommended.

Tarnishing’s a natural process called toning. When it
looks good, tarnishing can increase the value of the
coin.

If there’s dirt on your coins, you may be able to
remove it by soaking them for a few days in soapy
water or olive oil, then thoroughly rinsing with
water. Don’t dry them by rubbing them. Rubbing the
coin, even with a soft cloth will cause scratches.
