Cleaning Coins Found With Metal
DetectorsIt is
obvious to most coin collectors that there are some coins that
should never be cleaned. Valuable coins should be treated just
that way. Do not risk hurting the coin or damaging its' patina.
Clean these coins and the value drops dramatically. However, dug
coins are sometimes encrusted with dirt and materials from the
ground that cleaning will enhance their appearance and improve
their value. Here are a few techniques that work and will not
hurt the value of most dug coins.
Archaeologists in Europe who deal with ancient coin finds use
one or both of these methods. 1. Soak the coins in distilled
water and put them in your freezer. The water penetrates the
dirt and the ice crystals expand and break the dirt apart. It
may take several repetitions of the process to remove all of the
dirt; however, the coins are not damaged. 2. Lay the coins on a
piece of wax after covering them with a layer of Elmers white
glue. Let the glue dry thoroughly and then pull it off the
coins. A layer of dirt will be removed without damaging the
coins and again several repetitions are needed to completely
clean them.
Many silver coins and especially nickels come out of the ground
with black tarnish. The Mayors Cleaning method is great for
returning the sparkle to these coins. Go to the grocery store
and purchase a box of Arm & Hammer washing soda (not baking
soda) available in the laundry detergent section. Take a sheet
of aluminum foil and fold it into a 2-3 inch strip. Place it
into the bottom of a glass container and place the coins on top
of it. Place a couple tablespoons of the washing soda over the
coins and pour in boiling water till they are covered with about
an inch of water. After the fizzing, cleaning process has
stopped, take the coins out and rinse with water. You may want
to shine them up a little by rubbing them with a paste of baking
soda and water.
There are many soaking techniques and electrolysis methods of
cleaning dug coins and I will address those methods in a later
article. These are my favorite safe methods for cleaning coins
while enhancing their looks and value. Keep on building your
coin collection with these metal detector finds. Can you "dig
it"?
