Composition: Nickel-Brass (92% Copper, 6% Aluminum, 2% Nickel)

Brief Description
A copper-colored coin featuring an abstract map of France on the obverse and industrial/urban imagery on the reverse.
Historical Significance
Designed by Georges Mathieu, this coin was introduced in 1974 to replace the silver 10 Francs. It reflects the post-war industrial modernization of France and the 'Trente Glorieuses' period of economic growth. It was a staple of French currency until it was frequently counterfeited, leading to the introduction of a bi-metallic 10 Franc coin in the late 1980s.
Estimated Value
$0.50 - $2.00 in circulated condition; up to $10.00 in uncirculated (MS-63+) condition.
Care Instructions
Avoid cleaning the coin with chemicals or abrasives as this destroys the numismatic value. Store in an acid-free holder (PVC-free) to prevent corrosion.
Mint Mark
Cornucopia (Paris Mint) and Dolphin (Emile Rousseau, General Engraver)
Mintage & Rarity
Common; Approximately 80,000,000 were minted in 1980.
Weight & Diameter
10.0g / 26.0mm
Edge
Lettered (relief inscription: LIBERTE EGALITE FRATERNITE)
Apparent Grade
Fine to Very Fine. There is significant even wear on the high points of the abstract design and the rim is slightly bruised.
Obverse (Front)
An abstract, geometric representation of a map of France with intersecting lines and rays. The legend 'REPUBLIQUE FRANÇAISE' and the date '1980' are inscribed around the perimeter.
Reverse (Back)
Depicts industrial and urban motifs including a crane and stylized buildings. The denomination '10 FRANCS' is featured prominently in the center within a geometric framework. Artist signature 'MATHIEU' is visible.
What Drives This Coin's Value
Condition is the primary factor for this high-mintage year. Rare error varieties (such as those with edge lettering errors) or exceptional Uncirculated specimens command the highest premiums.
Similar Coins
10 Francs (Robert Cochey type) or the later bi-metallic 10 Francs. It is easily distinguished by its solid brass-like appearance and the distinct 'Mathieu' abstract art style.
Authenticity & Counterfeit Red Flags
Check for crisp edge lettering. This specific type was heavily counterfeited in the 1980s for use in vending machines; authentic coins should weigh exactly 10 grams and have a clear, non-mushy strike.
Notable Varieties & Errors
None common for 1980, though slight die shifts are occasionally found.
