This unused mint coin set from the Reiwa Era Year 2 (2020) features a unique face value of 666 yen, which is culturally significant and likely to intrigue collectors of Japanese numismatics.

The Japan Mint's limited editions typically see steady demand, particularly when the coins remain in pristine, unused condition, as with this set.

The outer box, showing minor wear, does little to detract from the overall appeal, emphasizing the challenge of finding well-preserved examples due to natural aging processes.

As Japan's mint often produces limited runs, collectors value these sets for their authenticity and connection to contemporary Japanese history.
