1 Jiao Memorial of Sun Yat-sen

This issue belongs to the flurry of memorial coinage produced following Sun Yat-sen's death in March 1925, as the Nationalist government worked to consolidate his image as the symbolic father of the republic. By 1927, Chiang Kai-shek had swept through the Northern Expedition and established Nanjing as the new capital — the political timing of memorial issues like this one was never incidental. Mintage figures for this denomination remain poorly documented, and surviving examples in any grade are genuinely scarce relative to the larger memorial dollar series struck concurrently.
