Defining a Die Stage
It is important to keep in mind the process of
cataloging die stages. Theoretically it is impossible to collect and
to list every stage of a die progression. The reason is that EVERY
coin struck by that pair of dies would have to be cataloged in order
for the listing to be complete - a task that is practically
speaking, impossible. Assume
for the sake of argument that you could put together such a set of
coins, or even a subset of say 1000 coins, and could line them up in
the order in which they were struck. In order for the variety to be
collectible (that is for others to be able to put together a similar
set), a decision would have to be made as to the degree of
difference between coin #1 and coin #1000. Assuming there is a
significant difference then Stage A and Stage B are born. There are
1000 coins between these two stages. The next question to ask is
just were is the dividing line between them. Is coin #500 a stage A
coin or a Stage B coin? I might be willing to part with coin #2 and
coin #999 because there just isn't much difference between them and
the true stages, but coin #500 is a different animal. So a third
stage is born. I now have stage A (Coin #1), stage B (Coin #500)
and stage C (coin #1000). So the process continues. Because of
just this problem, I have seen reference to Del Romine's die state
theory employing the terms EMDS and LMDS; Early Mid Die State and
Late Mid Die State. But the question still remains, just what does
it take to make a coin a different stage?
In practical experience,
there are some important factors to be considered. First, in any
given progression, only a mere handful of the average 1 million coins struck
by a particular die are examined. It is entirely possible that
major stages are missing from the listing. As more and more coins
are examined and compared to the listing, more and more stages will
be added. Second, the differences between say coin #1 and coin
#1000 are usually very slight. There are often thousands of coins
in a given stage. This is not always so, but is generally true.
So what does it take to
make a coin a different stage? It takes a significant difference;
a crack, chip, new die scratch pattern, etc. Each die has its on
unique deterioration scheme, so it has its on unique progression
listing. Until more than a small handful of coins are examined for
any given die, we'll have to live with the fact that our listings
and our collections are incomplete. In the meantime, new stages are
being discovered every day. Have you found any lately?
