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 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.
