1 Yen Aluminum Appraisal

Japanese 1 Yen Aluminum Coin

This is a circular Japanese 1 Yen coin, recognized as the lowest denomination of the Japanese yen currency. The coin is composed of 100% aluminum, which accounts for its lightweight nature and characteristic dull silver-grey appearance. The obverse side (displayed) features a young sapling, intended to symbolize the healthy growth of Japan. Above the sapling are the kanji characters for 'Japan' (日本国, Nippon-koku), and below it is the denomination 'One Yen' (一円, Ichi-en). The coin typically measures 20mm in diameter and weighs 1 gram. Regarding its condition, the coin shows signs of circulation and age, characterized by surface oxidation, pitting, and numerous small scratches scattered across the field and raised design elements. The edges appear somewhat softened from wear, and there is a noticeable buildup of grime or patina in the recessed areas surrounding the lettering and the sapling's leaves. The strike remains relatively clear despite the soft metal's susceptibility to damage. This specific design was first introduced in 1955 (Showa 30) and remains the current circulating design. The aluminum construction is a quality indicator of post-war frugal minting practices, designed to be cost-effective and light enough to float on water.
