How to Identify the Argentine 1 Peso 'Liberty Head'

What the Coin Is

This coin belongs to Argentina's silver peso series struck under the Moneda Nacional system in the 1880s and early 1890s. It is commonly referred to by collectors as the "Liberty Head" peso because of its classical allegorical portrait, distinguishing it from later Argentine peso types that used different imagery.

Obverse Design & Inscriptions

The obverse depicts a female Liberty head in profile, typically with flowing or upswept hair, sometimes wearing a simple headband or cap. The surrounding legend reads "REPUBLICA ARGENTINA," with the date placed below the portrait's truncation.

Reverse Design & Inscriptions

The reverse shows the national coat of arms: two clasped hands grasping a staff crowned with a Phrygian cap, set beneath a rising sun, encircled by a legend or laurel branches. The denomination "UN PESO" and "MONEDA NACIONAL" are inscribed around this central design.

Size, Weight, Metal, Edge

The coin is struck in .900 fine silver, weighing roughly 25 grams with a diameter of about 37 mm, consistent with the international silver crown-sized coinage standard of the late 19th century. Its edge is reeded.

Mint Marks & Where to Find Them

Examine the area below the date or along the coin's rim for small mint or engraver initials; Argentina's peso coinage of this period generally lacks a prominent separate mintmark, so the date and design style are the primary identifiers for narrowing down the exact year.

Telling It Apart from Similar Coins

Several countries issued Liberty-head silver coinage in the same general era, so confirm the "REPUBLICA ARGENTINA" legend and the specific clasped-hands-and-sun reverse, which are unique to Argentina. Comparing the hairstyle and cap details to reference images for the specific year can help pin down minor die varieties.

Judging Condition at a Glance

The highest points — the crown of the Liberty head's hair and the peak of the sun's rays on the reverse — wear smooth first. A well-preserved coin retains crisp curls in the hair and sharply defined ray lines; a heavily worn example shows a nearly featureless profile.

Authenticity Red Flags

Be cautious of coins with poorly defined lettering, an incorrect diameter or weight, or a bright, shiny surface inconsistent with naturally aged silver toning. A dull thud rather than a clear ring when gently tapped (using appropriate care) can also suggest a cast counterfeit rather than a genuine struck coin.
