Ringed bimetallic coins
Make these the 'center' of your attention
By Jeff Starck
Coin World Staff
Like a popular Hollywood movie franchise, sometimes coins have more than
Some coins with two parts are called ringed bimetallic coins.
A ringed bimetallic coin is a coin planchet assembled with two distinctly
different metal compositions, one as the outer ring and the other as the center.
The two pieces are locked together and jointly depict the images on the coin's
The basic idea of ringed bimetallic coins is not a new one. What is considered
by many as one of the earliest strikings of bimetallic prototypes dates back
to 1730, when a silver token with a center copper plug was struck in Cologne,
Germany, according to the Web site of the Worldwide Bimetallic Collectors
Club, at http://wbcc-online.com.
During the reign of Charles I, the English Rose farthing of 1625 to 1649
had a brass wedge inserted into the copper as an anti-forgery device.
Even the U.S. Mint got into the act, experimenting with silver center cent
coins in late 1782.
THE "TWOONIE" is the affectionate slang for Canada's $2 coin, which shows
a polar bear in the standard design.
Coins, at the core
The common method of producing a ringed bimetallic coin today calls for
the creation of two blanks that are joined together, the bimetallic Web site
There are several ways of joining ringed bimetallic blanks, with each manufacturer
having its own preferred method. The idea is the same: When the process is
complete, the two pieces should be tightly locked together.
More than 100 countries have made ringed bimetallic coinage, in many different
combinations of precious and base metals.
The first ringed bimetallic coin to be widely used in modern times was the
500-lira piece issued by the Italian government in 1982.
Much of the ringed bimetallic activity seems to center in Europe and in
France, Russia and Portugal all adopted ringed bimetallic coins in late
1980s or early 1990s. The United Kingdom soon followed.
France's entry into ringed bimetallic coins came in 1988, when it issued
10-franc coins depicting the Spirit of Bastille statue. Circulating versions
were struck with a steel core and an aluminum-bronze ring, and a collector
version was struck with a gold center and a palladium-silver alloy ring.
The USSR issued its first ringed bimetallic coins, 5- and 10-ruble pieces,
in 1991, shortly before the Soviet Union fell apart, and the Commonwealth
of Independent States continued the practice, issuing 10- and 50-rouble coins
in 1992 and 1993 (and until 1994 for the 50-rouble coin).
The United Kingdom added a ringed bimetallic £2 coin in 1998. In addition
to the standard design, which heralds new technology, a new commemorative
design is released every year. Precious metal versions of the coin have also
TWO DENOMINATIONS of euro coins, e1 and e2, use ringed bimetallic technology.
Shown are coins from Slovenia, the newest eurozone member to issue the multinational
Many euro offerings
Perhaps the most widespread issue of ringed bimetallic coins comes in the
form of the multinational currency known as the euro.
Currently, 13 nations use the joint currency, but eventually at least 25
nations will use the euro. The nations share common denominations with common
obverse designs, but each determines its own "national" side design featuring
artistic, cultural and historical themes or personalities unique to the issuing
The e1 and e2 coins are ringed bimetallic pieces, as the e1 coin has a copper-nickel
center and a nickel-brass ring, and the metal is switched for the e2 coin,
with a nickel-brass center and a copper-nickel ring.
Collectors will find numerous designs to choose from, though both denominations
of ringed bimetallic euro coins from several countries share the same designs.
Also, each country is allowed to issue commemorative e2 coins, one per year,
except for 2007 when each nation will also issue a joint commemorative honoring
the Treaty of Rome.
2000 LIBRARY OF CONGRESS Bicentennial $10 coin has a center of platinum
and an outer ring of gold.
Another one of the early modern adoptees of ringed bimetallic coins, Mexico,
is one of the most prolific.
Mexico joined the fray in 1992, issuing coins denominated 1-, 2-, 5- and
10-nuevos peso pieces with an aluminum-bronze center and a stainless steel
In 1993, ringed bimetallic 20-peso coins, with a silver center inside an
aluminum-bronze ring, made their debut along with 50-peso coins with a silver
center and a brass ring (now, the 20-peso coin has a copper-nickel center
and a brass ring).
A ringed bimetallic 100-peso coin (with silver center and aluminum-bronze
ring) was introduced in 2003 for a series of 32 designs honoring each of Mexico's
states and the federal district. Three versions of the coins were released,
including two ringed bimetallic coins (Proof versions of the 100-peso coin
have a gold center and a silver ring).
Mexico followed the conclusion of that series in late 2005 with a second
series of 32 designs (offered in the same versions) honoring the states and
the federal district, slated to end in 2007.
Up north, Canada has been issuing ringed bimetallic $2 coins more than 10
years. In 1996, Canada dropped the $2 note and replaced it with a $2 coin
showing a polar bear. Since then, the "twoonie" (a play on "two" and the slang
name for the Loon dollar coin, the "Loonie") has been quite popular.
That coin has an inner core of copper, aluminum and nickel and an outer
ring of nickel.
Several design variations are available for the interested collector, and
precious metal versions (of gold and silver in varying formats) have been
issued on more than one occasion.
U.S. tries its hand
The United States thus far has only issued one ringed bimetallic coin, a
platinum and gold $10 coin in 2000 to celebrate the Library of Congress.
Error versions surfaced shortly after the coin was issued. Coin World reported
on an off-center error coin in the May 29, 2000, issue. The platinum core
was positioned slightly off center during striking, and part of the metal
from the core flowed over the surface of the outer gold ring on the reverse.
More than a year later, a Sacagawea dollar coin struck on a hollow-center
planchet that was likely produced at the Royal Canadian Mint, surfaced. Coin
World reported on that in the Oct. 15, 2001, issue.
Out of the ordinary
To this point, you may have assumed that each coin has a round center, but
that's not always the case, as evidenced by the Australian 2001 gold and silver
$20 coin marking the Jan. 1, 2001, Centenary of the Australian Federation,
struck by the Perth Mint.
The seven-sided star in the center of the coin represents the seven states
In recent years. Austria has issued coins with a colored, niobium center.
Niobium is a shiny gray metal that takes on different colors when exposed
to air at room temperature for varying periods of time. Austria has issued
several coins using heat-treated niobium in various colors.
The world of these special coins isn't limited to two-part pieces: In 1992,
France upped the ante and added a ringed trimetallic coin, with a copper-aluminum-nickel
center, a nickel inner ring and a copper-aluminum-nickel outer ring.
France issued several of these ringed trimetallic coins in 1992 and 1993,
depicting animals, Mont St. Michel and the father of the modern Olympics Pierre
de Coubertin. Additionally, precious metal versions of the trimetallic coins
were struck with a gold core, a silver inner ring and a gold outer ring,
of varying finenesses.
Collecting these coins with parts is an interesting endeavor; the Worldwide
Bimetallic Collectors Club has hundreds of members from across the world.
It produces a weekly "newsmail" informing collectors of new issues and news
relating to the subject.
It also holds occasional auctions through the newsmail and annually stages
meetings at several large coin shows (including the American Numismatic Association
World's Fair of Money).
To learn more about the club, visit its Web site listed above. To further
explore the world of ringed bimetallic coins, consult coin books, like the
Standard Catalog of World Coins by Chester Krause and Clifford Mishler.

3. Quad-metallic 1 Royal 2007 from British Virgin Islands
by......Manuel Diez Gonzalez, Spain
In Pobjoy's webpage:
I could read:
British Virgin Islands World's First Quad Metal 2007 Coin
(British Virgin Islands Proof Quad Metal 1 Royal, Fine Silver, 4.65gms Palladium
3.90gms; Fine Gold 4.221gms; Platinum 2.78gms, --Ag/Pd/Au/Pt-- ; diameter
38.60mm, Weight, 15.551gms, Issue limit 999)
Announcing another world first from the pioneers of minting, Pobjoy Mint.
Now’s your chance to own the world’s first quad metal (that’s four metal)
coin, intricately crafted in rings of silver, palladium and gold, with a centre
of platinum, and produced on behalf of the British Virgin Islands.
It’s a must, not only for those collectors who are fans of groundbreaking
minting, but for those who love coins with an intriguing story. The value
of the coin is a royal, which is the English spelling of the Spanish Ryal.
This historic Spanish coin used to be cut into four to break it down into
smaller change. It’s from these Ryal quarters that the famous US Quarter got
its name. It’s in honour of the Ryal and the Quarter that Pobjoy Mint has
chosen to ‘quarter’ this new coin using four metals.
And that’s not the end of the story. Look at the beautifully intricate design
and you’ll notice it has a nautical theme, which ties in perfectly with the
seafaring traditions of the British Virgin Islands. The outer ring of the
coin depicts the points of a compass and includes a cross from the Spanish
eight Reale coin (which is better known to fans of pirate movies as a ‘piece
Inside this there’s more; a ship’s rope intertwined with blue marlins and
bottlenosed dolphins and the centre ring shows the sun with a ship from the
15th century. Sailors used to believe the earth was made up of four elements:
fire, earth, water and air – which takes us back to the theme of four at the
heart of this groundbreaking, superbly detailed coin.
This beautifully engineered and unique precious metal coin has been struck
four times to produce the superlative Pobjoy proof finish.

4. Multi-metallics, it’s all in the name......by Frans Woons, Canada
Contrary to the believe of some people, Bi-metallic coins are not new. An
early piece, e.g., is the US silver-centered cent dated 1792. Other early
pieces are the "model pennies" and "model halfpennies" made by Joseph Moore
in 1844. Most of these pieces are undated.
The recent flood of Bi-metallic coins and medals was triggered by Italy
when it decided to produce bi-metallic 500 Lire pieces as early as 1982.
Soon many countries followed.
In 1992 France introduced its tri-metallic 20 Francs piece and recently
the Pobjoy Mint produced a coin consisting of three concentric rings and
a plug. The Mint called this coin a "quad" coin.
Now the question has arisen: How do we call these types of coins? I propose
the following names:
* Uni-metallic: for normal coins struck on a homogenous planchet (a unicycle
has one wheel)
* Bi-metallic: for coins with two distinct parts: a ring of one metal and
a centre (plug) of a different type (a bicycle has two wheels)
* Tri-metallic: for coins with three distinct parts: two rings (one inside
the other) and a plug in the central hole (a tricycle has three wheels)
* Tetra-metallic: for coins consisting of three rings and a plug (a tetrahedron
is an object with four planes)
* Penta-metallic: for coins made with five pieces of metal; the Pentagon
has five sides
* Hexa-metallic: for coins made with six pieces of metal (a hexagon has
* Hepta-metallic: for coins made with seven pieces of metal. A hepta-metallic
medal could be admired recently at the World Money Fair in Berlin
* Octa-metallic: for coins made with eight pieces of metal (an octagon has
This seems to be sufficient for the time being... Of course this terminology
does not only apply to coins but also to medals.
The prefixes Uni, Bi, Tri, etc. are derived from the Latin or Greek.
