Coin consistent with a Colombian 10 Centavos piece

This object is a small, circular coin with a metallic silver-toned finish. On the visible obverse side, it features a right-facing profile of an indigenous figure wearing a feathered headdress. The edge of the coin is bordered by a raised dental pattern. Verbatim text appearing on this side reads 'DIEZ' to the left, 'CENTAVOS' to the right, and 'CALARCA' positioned below the bust. Based on the visible markings and design, the item is stylistically consistent with Colombian currency minted during the mid-20th century, specifically the Calarcá series produced between the 1950s and 1970s. The material appears to be a copper-nickel alloy, though this is unverified without physical testing. The condition shows moderate wear and circulation indicators, including soft edges on the relief details of the headdress and face, minor surface abrasions, and localized discoloration or patina. While the design is consistent with official mintage, the piece remains unauthenticated as a genuine government-issued coin from its era of origin without an in-person expert examination to verify its weight, diameter, and edge reeding.

Based on the provided imagery, I have examined this small metallic coin, which bears markings and a profile consistent with a Colombian 10 Centavos piece from the Calarcá series. From what I can see, the coin features the characteristic indigenous figure in a feathered headdress and includes the verbatim text 'DIEZ CENTAVOS' and 'CALARCA.' My evaluation is based on the hypothesis that this is a copper-nickel circulation strike from the mid-20th century, though I cannot verify its metallic composition or precise weight from a photo. The piece shows moderate wear, with softening of the high points on the headdress and facial features, which is typical for a coin that has seen significant circulation. The market for mid-20th-century Colombian base-metal coinage is generally very accessible, with high mintage numbers keeping values low for circulated examples. The estimated value reflects what a collector might pay for a representative specimen of this type. To confirm the status of this item, an in-person expert examination would be required to analyze the edge reeding, diameter, and weight to ensure it meets government specifications. If this piece were found to be a contemporary counterfeit or a modern replica rather than a government-issued coin, it would hold primarily novelty or reference value, likely less than one dollar. Conversely, if it were a rare variety or in uncirculated grade, which this example does not appear to be, the value could increase slightly. Given the common nature of this series, the value is driven more by historical interest than precious metal content or rarity.
