This 2019 Proof Coin Set, marking the final year of the Heisei era, will appeal to discerning collectors due to its significance in Japanese numismatic history and cultural transitions into the Reiwa era.

While items from the inaugural year of Reiwa often attract higher values, this set's pristine condition and inclusion of unused coins from Reiwa Year 7—rarely found in circulation—add notable collector interest.

The minting quality and presented craftsmanship reflect Japan's commitment to excellence in currency production, enhancing its desirability among collectors focused on historical context and scarcity in domestic markets.
