Brief Description
A bimetallic coin with a gold-colored center and a silver-colored outer ring. The coin shown has significant environmental damage/corrosion on the center plug.
Historical Significance
Introduced as part of the 'Nuevo Peso' revaluation in the early 1990s to stabilize the economy. The design elements draw heavily from Pre-Hispanic Mexican history, specifically the Aztec Sun Stone.
Estimated Value
$0.25 - $1.00 USD (Face value is approximately $0.25 USD. Significant corrosion on this specimen reduces any collector value to face value.)
Care Instructions
Do not attempt to clean the corrosion with chemicals as it will damage the metal surfaces. Store in a dry, PVC-free holder to prevent further oxidation.

M° (Mexico City Mint)

7.07g weight and 25.5mm diameter

Apparent Grade

Obverse (Front)
The National Shield of Mexico featuring an eagle perched on a cactus devouring a snake. Surrounded by the legend 'ESTADOS UNIDOS MEXICANOS' and a floral wreath.
Reverse (Back)
In the center, the denomination '5' and the '$' symbol. To the right, the mint mark 'M°'. The ring features a stylized design from the Ring of Serpents (Quiahuitl) on the Aztec Sun Stone.
What Drives This Coin's Value
Most influenced by the year of issue and the luster of the stainless steel ring. This specific coin's value is hindered by the heavy surface corrosion on the center.
Similar Coins
1, 2, and 10 Pesos are also bimetallic but differ in size and the specific Aztec ring patterns used on the outer border.
Authenticity & Counterfeit Red Flags
Check for magnetic properties (the ring is usually magnetic). Verify the weight (7.07g) and the clean join between the center plug and the outer ring.
Notable Varieties & Errors
None common for this denomination; collectors occasionally look for 'off-center' strikes or 'grease fills' in the die.
