It is one of four districts of the French Southern and Antarctic
Lands. The Crozet Islands were first discovered by the expedition of
Marc-Joseph Marion du Fresne, a French explorer, who landed on January
24, 1772 on Île de la Possession, claiming the archipelago for France.
He named the islands after his second-in-command Jules Crozet (He had
already named Marion Island after himself).
In the early 19th century, the islands were often visited by sealers, to
the extent that the seals had been nearly exterminated by 1835.
Subsequently, whaling was the main activity around the islands,
especially by the whalers from Massachusetts.
Shipwrecks occurred frequently at the Crozet Islands. The British sealer
Princess of Wales sank in 1821, and the survivors spent two years on the
islands. In 1887, the French Tamaris was wrecked and her crew stranded
on Île des Cochons. They tied a note to the leg of a Giant Petrel, which
was found seven months later in Fremantle. Alas, the crew was never
recovered. Because shipwrecks around the islands were so common, for
some time the Royal Navy dispatched a ship every few years to look for
France originally administered the islands as a dependency of
Madagascar, but they became part of the French Southern Territories in
1955. In 1961, a first research station was set up, but it wasn't until
1963 that the permanent station Alfred Faure opened at Port Albert on
Île de la Possession (both named after the first leader of the station).
The station is staffed by 18 to 30 people (depending on the season) and
does meteorological, biological, and geological research and maintains a
Mr. Zinkann designed pattern / trial coins on Crozet
Islands in various metals having 22 mm diameter and 1.0 mm thickness.
The CuNi Type II has 1.25 thickness with flat design. He got metal sheets from
Johnson Matthey in Boston, Massachusetts and then they were minted at
Pressed Metal Products.
These coins are known as Double Rooster 20
Francs commemorating the Year of Rooster. High Relief coins were
produced in Brass, CuNi Type I, Gold 18K Red and Silver metals.

Information on Molybdenum:
Atomic Number: 42, Atomic mass: 95.94 g/mol, Density: 10.28 g·cm−3, Melting
Point: 2623 °C. Molybdenum is a hard, heavy, grayish-colored metal that is
very corrosion resistant. The metal's primary use is as an alloying agent to
promote hardness in specialty steels used for high-speed cutting tools. It
is very resistant to corrosion by acids and many other corrosive materials.
Pure molybdenum thin sheet is used for x-ray tubes and electric furnaces due
to its resistance to high temperatures.
Information on Tantalum:
Atomic Number: 73, Atomic mass: 180.94788 g/mol, Density: 16.69 g·cm−3, Melting
Point: 3017 °C. Tantalum is an extremely hard, durable gray-colored
metal which has excellent corrosion resistance. With the right lighting and
surface texture Tantalum shows a definite pinkish tinge to its metallic
color. The metal has many uses including electrolytic capacitors, in alloys
to improve properties, and surgical and dental tools. It is a good crucible
material due to its resistance to corrosive materials. Tantalum has an
extremely high melting point, exceeded only by osmium, rhenium and tungsten,
and is also very dense.
