Japan
Manen gold Koban (Ryo) ND (1860-1867) AU, Edo (Tokyo) mint, KM-C22d, Hartill-8.26. Incredibly crisply struck with some slight cracks on the reverse, this is a truly choice example of this highly-debased (only slightly over 57% gold) and reduced (3.29g) issue--merely echoing the grandiosity of early types, though no less appealing.
