Mexican 20 Centavos copper-composition coin, as marked 1953

This is a circular metallic coin, appearing to be composed of a copper alloy such as bronze or brass, which is consistent with Mexican currency of the mid-20th century. The obverse shown features the large numeral '20' above a stylized central image of the Sun Pyramid of Teotihuacán, set against a background of volcanoes (Popocatépetl and Iztaccíhuatl). A Phrygian cap with rays is positioned between the numerals. The lower portion of the coin bears the verbatim text 'CENTAVOS' and the date '1953'. To the right of the text, a small 'M' with an 'o' above it is visible, which is consistent with the mint mark for the Mexican Mint (Casa de Moneda de México). The coin displays a significant dark brown patina and surface wear consistent with age and circulation. There are signs of minor pitting and localized oxidation, particularly around the date and denomination text. The edge appears to be plain rather than reeded, though this is difficult to confirm without a side view. While the markings are stylistically consistent with the 'Teotihuacán' type centavo issued by the Mexican government during this era, physical inspection would be required to verify its metal content and weight against official specifications.

Based on the image provided, the item bears markings consistent with a Mexican 20 Centavos coin, dated 1953, featuring the Sun Pyramid of Teotihuacán design. From the visual evidence, the coin shows a significant dark brown patina, surface wear, and localized oxidation, which is typical for a circulated mid-century bronze or copper-alloy coin. However, I cannot verify the weight, exact metal composition, or edge details from a photograph alone. My estimate is based on the working assumption that this is a period striking by the Casa de Moneda de México as the mint mark suggests. In the current numismatic market, common circulated examples of the 1950s 20 Centavos series are widely available and carry very modest premiums, typically trading as inexpensive collector items or bulk foreign coinage. The condition noted here—specifically the pitting, wear, and oxidation—limits its appeal compared to uncirculated examples. To determine its actual status, in-person examination by a numismatic professional would be required to evaluate its exact dimensions, weight, and metallic content. Because these coins are common and of low base value, they are rarely reproduced for deception; however, if this piece were determined to be a contemporary copy or novelty item rather than a government-issued coin, its value would be negligible. The estimated range reflects the typical retail value for an item of this type and condition, assuming the hypothesized attribution holds true.
