Since I am not intimately familiar with your
set up I will answer the question as best I can.
I found a
simple procedure on the Internet that utilizes a
9-volt battery and items you can purchase at your
local drug store. With this procedure you can
plate pennies with zinc, bismuth, and mercury. But
you can also use the solution you already have of
silver nitrate in order to plate silver on the
Here is what you do:
1. Fold a paper towel up into a 1"x 1" square.
Fold aluminum into a 0.5 inch square with the
thickness of a penny.
2. Put four drops of calamine lotion in a
small beaker. Add some vinegar to the solution. I
am not certain what the optimal amount of vinegar
is so you should test it out with 4 drops first
and then increase the amount of vinegar you add to
the solution in order to get the best result. Stir
the mixture and pour it on to one end of the
folded paper towel.
3. Make approximately 25 mL
of a saturated sodium chloride solution. Pour this
solution on the other end of the paper towel. The
salt solution should be touching the calamine
portion of the paper towel.
4. Place a clean
penny on the calamine portion of the paper towel
and place the aluminum foil on the paper near the
penny. Invert the 9-volt battery and place the
large terminal on the penny and the smaller
terminal on the aluminum foil. You will probably
secure the battery with a long piece of electrical
tape. Leave the battery on the set up for
approximately 5 minutes.
5. Remove the battery
from the set up and dry the penny. It should be
coated with zinc.
6. You can repeat this
procedure using different paper towels, metals,
and solutions. There is a list below.

Bismol. This will coat the penny with

can cause heavy metal poisoning. Wear gloves at
all times while handling the Mercuroshrome stain.
Only use a small amount of the stain. Be sure to
read the label of the stain before use.
