This set of 22 one-yen coins from 1955 represents an important piece of Japanese numismatic history from the Showa era, illustrating the country's economic evolution following World War II.

Aluminum was used for production during this period due to material shortages, making these coins a unique artifact of their time.

Collectors appreciate their historical context and design, which captures the essence of mid-century Japan.

Given their good condition and original issue status, they hold intrinsic value for both numismatists and those interested in post-war Japanese culture.
