1837-58年日本天保小判金。 此版而言极致诱人,无甚经手痕跡,底板乾净,边缘一丝虹彩。 </p> JAPAN. Koban (Ryo), ND (1837-58). Tempo Era. PCGS AU-55. Fr-15; KM-C-22b; JNDA-09-21; JC-03-22. Incredibly attractive and inviting for the type, this barely handled specimen presents rather clean fields that are free from much in the way of handling and that sport a hint of iridescent toning near a portion of the peripheries.
