| Additional information |
The Hōei Mameitagin was an emergency debased issue, produced after the Tokugawa Shogunate had progressively degraded silver coinage fineness across the late 17th and early 18th centuries. By 1710, the bean silver had dropped to roughly 32% — a dramatic fall from the near-pure Keichō standard of a century earlier. The shogunate's chief advisor Arai Hakuseki condemned the debasements publicly, and his criticism directly precipitated the monetary reforms of 1714 that pulled these pieces from circulation after barely a year of production.
The "Large 宝" designation distinguishes this by die stamp size — a meaningful variety distinction, not a decorative one.
