This unopened roll of 50 one-yen coins from Showa 64 is a remarkable representation of Japan's limited minting history, specifically spanning just eight days from January 1 to January 8, 1989, marking the transition into the Heisei era.

The rarity of this coin roll stems not only from its brief production window but also from its potential historical significance, as Showa 64 is often overshadowed by the events that followed.

Condition-wise, while some dirt on the edges may affect aesthetic appeal, the unopened status is crucial for collectors focused on preservation and authenticity.

Given its unique attributes and Japan's long-standing appreciation for numismatic items, this roll is likely to attract serious interest from collectors seeking to expand their historical currency portfolios.
