Coin of Guatemala, dated 1964 as marked

This item appears to be a circular circulation coin from Guatemala, bearing a marked date of 1964. The obverse side shown features the coat of arms of the Republic of Guatemala, which includes a quetzal bird perched on a scroll, crossed rifles, and crossed swords within a laurel wreath. The text bordering the upper edge reads 'REPUBLICA DE GUATEMALA', and the year '1964' is visible at the bottom. The scroll within the central crest bears partially legible text that typically reads 'LIBERTAD 15 DE SEPTIEMBRE DE 1821'. The coin exhibits significant signs of wear and environmental exposure, including dark surface patination, oxidation, and possible corrosion (verdigris) visible as light-colored spots. Physical features such as the copper-toned appearance are consistent with a bronze or copper-nickel composition typical of mid-20th-century fractional currency. The edges show considerable softening of the relief, suggesting a period of circulation. This identification is based on visible markings and iconography, but the item's composition and exact numismatic status cannot be verified without physical inspection to confirm weight, diameter, and edge reeding.

I have examined the image provided of a circular coin bearing markings consistent with a 1964 Republic of Guatemala issue. Based on what I can see, the piece features the national coat of arms and carries the 1964 date. While the iconography matches the profile of a fractional unit, such as a 1 or 5 centavos piece, I cannot verify the exact denomination, weight, or metal composition from a photograph alone. The surface exhibits significant wear and what appears to be oxidation or environmental corrosion, which notably impacts its numismatic appeal. My valuation reflects a working assumption that this is a common-date circulation coin. The market for mid-20th-century Guatemalan currency in this condition is generally very accessible, with items often trading as nominal collector pieces or bulk numismatic stock. The stated value range is for an item of this type assuming it is an official mint issue; if physical inspection were to reveal it as a modern token or copy, the value would be negligible. To form a more precise conclusion, an in-person examination is necessary to check the diameter, weight, and edge reeding. Authenticity cannot be asserted without verifying these physical properties against official mint specifications. Generally, demand for fractional coins of this period in circulated condition remains low, as collectors typically seek higher-grade specimens with minimal surface damage.
