Coin Pièce Costa Rica 25 colones Nickel-brass 2023

The 25 colones coin issued by Costa Rica in 2023 belongs to the series dedicated to the country's provinces, featuring the province of Alajuela and its iconic Arenal volcano. This volcano, located in the northwest of Costa Rica, is one of the most active volcanoes in Central America and represents a major geographical and cultural landmark of the Costa Rican territory.

Struck in nickel-brass, an alloy recognisable by its characteristic golden reflections, this coin has a diameter of 22.5 millimetres and a weight of 4.3 grams. These dimensions place it in a standard format, suitable for everyday circulation. Nickel-brass is an alloy frequently used in contemporary coin minting due to its durability, corrosion resistance and electromagnetic properties that facilitate automated detection in currency processing equipment.

The obverse of the coin most likely features the institutional elements associated with the issues of the Banco Central de Costa Rica, the institution responsible for national monetary issues. The reverse highlights the Arenal volcano, whose conical profile is one of the most recognisable in the region, often depicted with its characteristic volcanic plume. This representation is part of an approach to showcase the natural and geographical wealth of the country's various provinces through circulating currency.

The face value of 25 colones represents an intermediate denomination within the Costa Rican monetary system. The 2023 issue reflects the continuation of a local minting policy tied to the territorial and heritage identity of Costa Rica, linking powerful natural symbols to coins intended for circulation.
