This meticulously organized collection of modern Japanese coins features important pieces from the Heisei to Reiwa periods, with an emphasis on rare proof coins that are highly coveted among numismatics enthusiasts.

The limited circulation of certain 1 yen and 5 yen coins has driven up demand, with some individual proof coins commanding prices significantly higher than their face value, reflecting their scarcity in the market.

Such coins often resonate with collectors not only for their historical significance but also for their aesthetic design and the precision of their minting, representing Japan's rich numismatic heritage.

The premium pricing on this auction highlights the collector community's recognition of these artifacts as valuable representations of Japan's monetary evolution.
