The United States
Mint is investigating why edge collars featuring two different
reeding styles were used at the West Point Mint to strike 2015
American Eagle tenth-ounce gold bullion $5 coins.
Numismatic Guaranty Corp. posted photographic evidence Jan. 22 on
its website to
illustrate the differences in what the grading service is attributing
as the Wide Reeds and Narrow Reeds edge varieties.
NGC claims this is the first time that a variation in reed sizes on
the edge of any American Eagle bullion coin has been noted.
World has requested an explanation from the U.S. Mint as to
why two different style collars (the part of the die setup that
produces the edge-reeding) were used and the reed count for each.
The Wide Reeds variant has the standard size reeding produced by
edge collars used in the production of American Eagle gold bullion
coins in prior years.
The Narrow Reeds edge style, according to NGC, exhibits “much
smaller and finer reeds that are more tightly spaced than those seen
on prior issues."
This is the first time the Narrow Reeds edge style has been used on
American Eagle tenth-ounce gold bullion coins, according to NGC.
The standard Wide Reeds variety appears more abundant in the coin
submissions to NGC thus far for the 2015 tenth-ounce gold coins.
All four sizes of 2015 American Eagle gold bullion coins first went
on sale from the U.S. Mint to authorized purchasers in the first week
All American Eagle bullion coins are struck at the West Point Mint, but without the W Mint mark.
Three dies used in the production of the American Eagle coins — an
obverse, a reverse and an edge or collar die.
The collar die restrains the flow of metal of the planchet during
striking to retain a uniform diameter. The edge design on most coins
is imparted during striking, whether plain, reeded, or ornamented in
some other form.
“Traditionally, reeds were used on precious metal coinage to
indicate during circulation that no metal had been removed from a
coin’s edges,” according to NGC. “This feature, along with raised edge
lettering, has been employed on all precious metal U.S. coins since 1836.
“All American Eagle coins have reeded edges,” the remarks from NGC observe.
