Mid-20th-century Colombian 20 centavos-style coin

This item is a circular coin or token, which appears to be struck in a base metal such as copper-nickel or a similar silver-colored alloy. The obverse features a right-facing profile bust of a male figure, appearing to be in the style of Simón Bolívar, surrounded by the arched inscription 'REPUBLICA DE COLOMBIA'. Below the bust is the date '1956', flanked by two small five-pointed stars. The rim is decorated with a beaded or denticulated border. The surface exhibits significant wear and tear consistent with age and circulation, including numerous small scratches, surface abrasions (especially in the field around the portrait), and a dull, greyish patina. There is some heavier impact damage or nicking visible on the lower-left edge of the rim. While the markings are consistent with a 20 centavos piece issued by the Republic of Colombia in the mid-20th century, this identification remains a hypothesis based on visual evidence. These markings have not been verified through physical metallurgical testing or expert numismatic inspection to confirm their origin or material composition.

Based on the provided imagery, I have examined this circular coin which bears markings consistent with a Republic of Colombia 20 centavos piece dated 1956. The piece features a profile bust in the style of Simon Bolivar. From what I can see, the coin exhibits significant circulation wear, dull patina, and several rim dings, which directly impact its numismatic appeal. I cannot verify the specific metal composition or the exact weight from a photograph, both of which are necessary to confirm if this is a standard circulation strike or a contemporary counterfeit. The value estimate is reflective of a common-date mid-century South American circulation coin in 'Very Good' to 'Fine' condition. General market demand for this specific year and denomination is relatively low among collectors unless the piece is in exceptional, uncirculated state, which this example is not. To confirm the origin and potential value, an in-person numismatic inspection is required to check for minting errors or specific die varieties. If this item were found to be a modern base-metal reproduction or a non-period token rather than a government-issued coin, its value would be negligible, likely under $0.10. Conversely, if it possessed a rare mint mark or die rotation not visible here, the value might slightly increase, but given the visible surface damage and high mintage for this type, it remains a low-value specimen for entry-level collectors.
