| Additional information |
The Genroku Mameitagin was struck as a debased replacement for the earlier Keicho silver, which the Shogunate recalled in 1695 under Tsunayoshi. The new issue dropped silver fineness from roughly 80% to around 64% — a deliberate debasement that generated enormous seigniorage profit for the Edo treasury while the public received face-equivalent replacements for their higher-quality coins. The policy was controversial enough that it is specifically documented in Arai Hakuseki's economic critiques of the Genroku administration.
The bean-shaped (mamei) format was cast and individually hand-stamped, meaning no two pieces share identical dimensions or stamp placement. The 元 mark denotes the Genroku era designation added to authenticate this specific emission.
