This commemorative Proof Coin Set celebrates the 50th anniversary of the Pencil Rocket, a significant piece in Japanese pop culture history, also tied to the 1 Yen Aluminum coin introduced in 1955.

Coins manufactured by Japan's Mint Bureau are known for their high quality and attention to detail, appealing to numismatics collectors focused on commemorative items.

Although the set shows minor signs of aging, including scratches and discoloration, its limited edition status and the historical importance of both the Pencil Rocket and the 1 Yen coin can enhance its collectability among enthusiasts.

Given the current bid of ¥15,000, this set offers an accessible entry point into a niche segment of Japanese collectible coins.
