Circulated 1974 Guatemalan coin

The image shows the obverse side of a circular coin consistent with 1974 Guatemalan currency. The coin appears to be made of a silver-toned base metal, such as copper-nickel. It features the national coat of arms of Guatemala in the center, which includes a resplendent quetzal bird perched on a scroll, crossed rifles, and crossed swords within a laurel wreath. The text around the upper perimeter reads 'REPUBLICA DE GUATEMALA' in capital letters, and the date '1974' is stamped at the bottom. The scroll in the center bears the visible text 'LIBERTAD 15 DE SEPTIEMBRE DE 1821'. The coin shows signs of circulation including surface scratches, minor pitting, and light tarnish along the edges. Based on the visible markings, it is stylistically consistent with a 5 or 10 centavos piece from that era, though the reverse side would be needed to determine the denomination. No claim of authenticity is made, as physical composition and weight cannot be verified from the photograph.

I have examined the image provided of what appears to be a 1974 Guatemalan coin featuring the national coat of arms. Based on what I can see, the coin bears markings consistent with a copper-nickel 5 or 10 centavos piece. I cannot verify from a photo the specific denomination, weight, or metallic composition, which are vital for a comprehensive valuation. The item shows clear signs of circulation, including surface scratches, minor pitting, and tarnish, which typically places such a specimen in a 'Fine' to 'Very Fine' grade range. These coins were minted in high volumes for general commerce, and as such, they are common in the secondary numismatic market. The value estimate is based on the assumption that this is a standard circulation issue; if it were a rare mint error or a proof striking—which I cannot determine here—the value would increase. Conversely, if the metal content is found to be non-standard upon physical inspection, the value would be negligible. To confirm its status, an in-person examination by a numismatist to verify weight, diameter, and edge reeding is required. Market demand for circulated mid-20th-century Guatemalan base-metal coinage is generally low, often appealing primarily to budget-conscious type set collectors. The value of an unauthenticated or replica piece of this nature is effectively zero, as the cost of shipping often exceeds the item's market worth.
