Description
This is a 100 Pesetas coin from Spain, commonly referred to as a 'duro' in larger denominations or part of the 'Peseta' family. It features the profile of King Juan Carlos I, who reigned from 1975 to 2014. Despite its metallic luster, it is an aluminum-bronze alloy used for circulating currency and possesses no bullion silver value. The 1982 issue is particularly common as it coincided with Spain hosting the FIFA World Cup.
Key Features
Portrait of Juan Carlos I, '1982' date stamp, aluminum-bronze composition (distinctive golden-hue), 24.5mm diameter.
Material & Composition
Aluminum-Bronze (NOT SILVER). It contains 88% copper, 5% aluminum, 5% zinc, and 2% manganese. Unlike previous 100 pesetas coins which were silver or nickel, this 1982 issue has zero silver content.
Finish & Decoration
Die-struck finish with a yellowish-bronze appearance often mistaken by novices for gold or tarnished silver. The obverse features the left-profile portrait of King Juan Carlos I. It includes a reeded/milled edge for anti-clipping security.
Hallmarks & Stamps
The 'M' with a crown (the mint mark of the Madrid Mint) is typically found on the reverse. The inscription reads 'JUAN CARLOS I REY DE ESPAÑA' with the date '1982'. No precious metal hallmarks exist because the item is base metal.
Construction Details
Machine-manufactured through industrial die-striking. High-pressure hydraulic presses strike blank planchets with hardened steel dies.
Functional Features
Legal tender in Spain prior to the adoption of the Euro in 2002. Features a raised rim and reeded edges for tactile identification and to prevent shaving of the metal.
Handle & Grip Details
None (standard round coin with milled edges for grip).
Craftsmanship Details
Standard industrial minting. High quality for mass-produced currency, with sharp lettering and consistent weight, though lacking the artistry of hand-wrought silver pieces.
Authentication Indicators
The typography, profile likeness, and specific 1982 date placement are consistent with genuine FNMT production. The lack of silver hallmarks is correct for this specific denomination and year.
Origin & Manufacturing
Spain; minted in Madrid at the Fábrica Nacional de Moneda y Timbre (FNMT).
Era & Period
Constitutional Monarchy / Transition Period in Spain. This specific design was introduced in 1982 during the reign of King Juan Carlos I.
Age Estimate
Dated 1982; 42 years old as of 2024.
Cultural Significance
Represents the economic history of Spain and the stabilizing presence of the monarchy during the country's transition to a modern European democracy.
Condition Notes
Fair to Good. The surface shows significant circulation wear, fine scratches (hairlines) across the field, and typical oxidization/tarnish associated with base metals. No significant dents, but the detail on the hair and ear is softened.
Value Estimate
Nominal/Numismatic only. Approximately $0.50 to $2.00 USD depending on local demand. It has no silver melt value and is no longer legal tender since it was demonetized in 2002.
Care & Maintenance
For circulation coins of base metal, cleaning is generally discouraged by numismatists as it removes original patina. If necessary, use warm soapy water and a soft cloth. Store in a dry environment to prevent verdigris (green corrosion).
Similar Pieces
1966 100 Pesetas (which is 80% Silver), or modern 1 and 2 Euro coins which replaced the peseta. Many tourists mistake these bronze-colored coins for gold or silver due to the luster.
Interesting Facts
The 100 pesetas coin was often referred to as a 'Billete de 100' informally before 1982 when it was primarily a banknote. The 1982 coins are historic because they circulated during Spain's first democratic decade after the Franco era.
