Costa Rican coinage, as marked 1958

This object is a circular metal coin featuring a silver-colored finish, possibly composed of a copper-nickel alloy or stainless steel, which is consistent with mid-20th-century Central American circulation currency. The obverse depicts the national coat of arms of Costa Rica, showing three volcanoes and two merchant ships under a row of five stars, enclosed within a shield. The text 'REPUBLICA DE COSTA RICA' is embossed around the upper perimeter in a serif font, while the date '1958' is embossed at the bottom. Small, barely legible text above the shield appears to read 'AMERICA CENTRAL'. The coin shows signs of moderate wear, including surface scratches, minor pitting, and softened details on the higher relief areas of the coat of arms. There is visible dirt or oxidation settled in the recessed areas of the design. The rim appears slightly rounded from use. While the markings are clearly visible, the item remains unverified as a genuine mint product without physical weight, diameter, and magnetic testing by a numismatist to rule out contemporary or modern counterfeits. Identification is based on the legible embossed text and iconography.

Based on my visual examination of the provided image, this object bears markings consistent with a 1958 Costa Rican coin, likely a 50 céntimos or 1 colón denomination depending on its physical diameter. I can observe the national coat of arms and the date '1958', but I cannot verify the metal composition or weight from a photograph alone. These details are critical for determining if the piece is a standard circulation strike or a potentially rarer variety. The item shows moderate wear and surface oxidation, which places it in a circulated condition category. The market for mid-century Central American base-metal coinage is generally stable, with values driven by collectors of world currency. My estimate assumes the item is a standard government-issued product; however, because I cannot conduct a physical inspection for weight, edge lettering, or metallic density, this attribution remains a hypothesis. If the piece were identified as a modern replica or a counterfeit upon physical testing by a numismatist, its value would be negligible. Conversely, if it were a high-grade specimen with minimal wear, the value might sit at the higher end of the range. To establish a more precise value and confirm its nature, an in-person examination to rule out contemporary counterfeits and a measurement of the diameter to determine precise denomination are required.
