Notes: This
experimental rinse/finish attracted much attention when it was
discovered on 2001-P Sacagawea Dollars. Coin World attempted
to contact the Mint to get the details on this experimental process,
but Mint officials refused to comment. The June 25th Issue has a
detailed article on this discovery. This discovery was also
featured in Numismatic News in their June 5th Issue. They
were the first to report on these experimental Sacagawea
Dollars.
As everyone knows, the year
2000 Sacagawea Dollars, which was the first year of issue, were
plagued with spots, discoloration, and tarnish, even when pulled
from bags or rolls from the bank.
The Sacagawea Dollar has an
alloy layer on each side of the copper core. These two layers are
manganese bronze, a composition the U.S. Mint has not used since
Wartime Nickels were being struck in the early 1940's. The Mint
experienced many problems with the Wartime composition, which
peeled, laminated and was not mixed properly.
A similar situation occurred
in 1999, when the Mint was experimenting with the composition,
layers and finish for the alloy to be used for the Sacagawea Dollar.
The end result was an overall composition of 88.5% copper, 6% zinc,
3.5% magnesium and 2% nickel.
There have been several
articles in Coin World in the last year which have described in
detail the problems that the U.S. Mint was having with the
composition and finish of the new Sacagawea Dollar. In one of the
recent articles, Michael Fahey of ANACS describes the finishing
process for the burnished Sacagawea Dollars, explaining that the
rinse was "used to remove any surface residue from the coins, and to
prevent spotting."
Recently on the Discovery
Channel, there was a program exclusively devoted to the U.S. Mint
and the production of United States coinage. In this film, viewers
got a close up look at the entire minting process. This program
included an interview with the Mint Director regarding the new
Sacagawea Dollars. It also elaborated on the tests and experiments
that were conducted by the Mint on this new alloy for the Sacagawea
Dollar. Small quantities of blank planchets and struck coins were
subjected to chemical testing, exposure to artificial sweat,
mechanical wear and tear, artificial wear and electrical
testing.
Knowing that the Sacagawea
Dollar in it's first year of production was plagued with these
problems, the U.S. Mint continued to experiment and conduct tests on
the surface with chemicals and rinses to ensure that future years of
production would not have similar problems. This small hoard was
discovered through the normal distribution channels by an alert
employee/collector who instantly noticed that these were different
in color, appearance and texture. This individual contacted David
Hendrickson of Silver Towne, one of the largest coin dealers in the
Mid-West, and subsequently sold these discovery pieces.
This group was then
authenticated and certified by SEGS (Sovereign Entities Grading
Service) as having an Experimental Rinse. SEGS is one of the leading
certification and grading services. One of their specialties is
Major Mint Errors. Larry Briggs, the owner of SEGS, is a highly
respected numismatist. One of the authenticators of Mint Errors for
SEGS is Bill Fivaz, a well known mint error specialist. After an
unsuccessful attempt at reaching the Mint for comment, Larry Briggs
consulted with several Mint Error specialists and determined that
"these coins were the result of an experimental rinse or
finish."
Another world renowned Mint
Error expert, Fred Weinberg, has examined some of these experimental
pieces and agreed that they have "an experimental rinse or finish."
This rinse/finish was applied by the United States Mint to hopefully
eliminate the spots and discoloration.
These Experimental Sacagawea
Dollars are being sold exclusively by Michael S. Byers of Byers
Numismatic Corp. and are available only through http://www.byersnc.com/, the
company's website. These authenticated and certified experimental
pieces have been graded Mint State 64 to Mint State 67 and are
priced between $150 and $300.
On November 18, 2000 the
United States Mint struck approximately six hundred Sacagawea
Dollars on a special press for dignitaries, collectors, and other
invited guests. These special presentation strikes are referred to
as VIP strikings and have sold on eBay for $600.
Glenna Goodacre, who was the
designer of the obverse for this new dollar, was paid by the U.S.
Mint in the form of five thousand Burnished Sacagawea Dollars. These
Burnished specimens were certified by ICG and sell on eBay in the
$500-$600 range. ICG certified all five thousand of these Burnished
Dollars with this special surface.
