This complete set of 11 proof coins from the Japan Mint, spanning Heisei 23 (2011) to Reiwa 3 (2021), offers collectors a rare glimpse into Japan's currency evolution during a transformative era.

Coins issued in 'special years' often command higher interest due to their unique cultural significance and limited release, enhancing their collectability.

While the outer packaging shows wear from long-term storage, the coins themselves remain well-preserved in their original cases—a crucial factor for numismatic collectors, as condition significantly impacts value and desirability.

Given the current bid of ¥29,800, this set presents a compelling opportunity in the Japanese numismatic market, reflecting authentic, domestic production valued by serious collectors.
