Hello to everyone again. Well, in
case you're wondering why I'm not here, it's because I'm in class. Nope,
it's not a numismatic class, it's the Cultural History of Europe. I
think it may help me debate with Guy! Well I doubt it, anyway,
I will try to remain active within our organization as best as I can. I'm
attempting to finish something I started a long time ago and if I make
it, you're all invited to the party! Well, as long as you
bring gifts. Just kidding. Anyway, being a college
kid again is not as easy as it used to be, so please keep me in your
prayers.
Now on the lighter side, again I must state
that I'm the farthest from a numismatic expert as you can get so I appreciate
this joint learning experience. I would appreciate an opportunity
to share with you and I have been looking in vain for a written response
on the last newsletter. This is certainly sad because I had
a whopper of a prize waiting to be awarded. Don't get me
wrong, I appreciate keeping it! Well I won't promise you
anything for this month's questions but I will promise you will learn
something so, send in that mail!
Introduction
Last month we covered the introduction of the
minting process. You remember planchets! Well
I hope you remember. This month we will cover a very important
process. The galvano! Well we will be looking
at the design process. Can you name three important artists
to the world of numismatics? Just think, all of those beautiful
works of art reduced to a lowly galvano. I wonder, is that
Italian? Sounds like it might be. Perhaps someone
will check the root and let me know. When the moon hits your
eye like a big galvano pie that's amore! At least it is to
a numismatist.
The Design Process
Understanding the design process is the key
to a genuine understanding of grade, condition, errors, varieties and
all the other attributes of numismatics. Do you remember
Alan Herbert's PDS system and the three production areas in the mint,
planchets, die manufacture and striking? Which would you
place the design process in?
First we start with artists. Well
what did you think engineers? Fooled you didn't I? Now,
artists may be employed directly by the Mint or they may be contracted
by the Mint to produce specific artistic pieces. Sometimes
this is done through contests like our recent state quarter designs. Can
you name one of the most famous artists the Mint ever contracted to
design a coin? Can you name a famous artist that was employed
by the Mint?
The artists employed by the mint are sculptors
and engravers and their job is to transform a design from a drawing,
painting, or other two-dimensional object into a plaster model. The
model is approximately eight inches in diameter and completed in relief. Relief
means the image is raised like on a coin. After the design
is completed, rubber is poured over it and allowed to harden. Once
the rubber is hardened an epoxy resin is poured into the rubber mold
forming an epoxy shell. This epoxy shell, our galvano, is
then forwarded to the die making area of the Mint.
So now some of you are wondering how is it that
I can call an epoxy shell a galvano. The reality that it
isn't a galvano is true but for lack of a better term, the old term
has simply hung around. Galvanos are copper shells that used
to be made from the plaster molds. The models were covered
in wax and dipped into an electrically charged bath containing copper. The
copper formed a replica of the artistic rendition of the model. This
copper rendition was known as a galvano because it was made through
the electromagnetic galvanic process. There have been some
changes over the years as to what is to be included on the plaster model
so that when the galvano is made it reflects these attributes. Anyone
care to guess? Okay, they used to repunch them. By
law or custom, certain features must appear on our coins. Do
you know what they are?
Homework
You may turn in your homework in writing at
the next meeting. Or if you prefer, you may mail it. Who
knows, you may receive an honorable mention in the next newsletter. Thank
you for the privilege of allowing me to serve and as always, good luck
in your search.
