This specimen was lot 57456 in Stack's Bowers NYINC sale (New York, January 2024), where it sold for $288. The catalog description<sup>[1]</sup> noted, "[[Japan|JAPAN]]. Bu, ND (1837-58). Tempo Era. PCGS MS-63." The dating of hammered and cast coinage of Japan is confusing. The SCWC states that the coins were not necessarily made during the era to which they are marked. Not all the eras have coinage. The SCWC notes the following:

* Genbun period 1736-41 (used on coinage 1736-1818), emperor was Sakuramachi-tennō (桜町天皇).
* Meiwa period 1764-72, empress and emperor were Go-Sakuramachi-tennō (後桜町天皇) and Go-Momozono-tennō (後桃園天皇).

* Tenmei period 1781-89, emperor was Kōkaku Tennō' (光格天皇).
