Numismatic coin consistent with Guatemalan currency, 1965

This item appears to be a circular metal coin featuring the national emblem of Guatemala on its obverse side. The central motif depicts a Resplendent Quetzal perched on a scroll; the scroll bears the text 'LIBERTAD 15 DE SEPTIEMBRE DE 1821'. This emblem is flanked by Remington rifles and swords, all enclosed within a laurel wreath. The upper arch of the coin bears the inscription 'REPUBLICA DE GUATEMALA', and the bottom features the date mark '1965'. The coin shows a silvery metallic luster, suggesting a composition consistent with silver alloy or cupronickel coinage common for that era. There is visible surface wear, including minor scratches, softening of the higher relief details of the quetzal and wreath, and a significant dark patch of oxidation or surface debris near the 'REPU' lettering. The edge of the coin appears to have a beaded or denticulated rim. This object is stylistically consistent with the 5, 10, or 25 centavos denominations issued by the Banco de Guatemala around the mid-20th century, though physical diameter and weight are necessary to determine the exact denomination. The attribution is based on visible markings that correspond with historical national symbols, though its status as a government-issued strike remains unverified without physical inspection.

Based on the provided imagery, the item displays characteristics consistent with a 1965 Guatemalan issue, possibly a 25 centavos denomination given the commonality of the design. However, I cannot determine the exact denomination, weight, or metal composition from a photo alone. The coin's luster suggests a silver content typical of the period, but I cannot verify if this is a silver strike or a later base-metal equivalent without a physical measurement of its mass and diameter. The presence of surface wear and significant oxidation or debris near the 'REPU' lettering negatively impacts the potential grade. My value estimate is based on the assumption that this is a circulation-strike coin of this era in average circulated condition. The market for mid-20th-century Guatemalan coinage is generally stable but depends heavily on the specific silver content and the degree of preservation. To establish a more precise value, an in-person examination by a numismatist would be required to verify the strike, check for edge details, and perform a density test. This would also rule out the possibility of it being a contemporary replica or a common metal copy. If the coin were to be identified as a rare variety or in a significantly higher state of preservation, the value could increase; conversely, if it is a non-precious metal reproduction, it would hold primarily decorative or nominal curiosity value. Documentation regarding its provenance or a professional grading service slab would be necessary to confirm the grade and the metallic legitimacy of the piece.
