<p>[QUOTE=&quot;Mrktstrtmyhm, post: 7996625, member: 118005&quot;]I&#039;ve had my eyes on Koban for a while now and Jane&#039;s Auction World in Tokyo just had a great auction with plenty of fine examples on display. I was able to snag a Tempo Era koban and received it yesterday and was really really satisfied with the way Auction World shipped the coin and how it is presented! Here is a little info on this particular type of Koban: </p><p><br /></p><p>JAPAN, Tempo Era. Edo (Tokyo) mint, c. 1837-1858 AV Koban, 11.22g (31mm x 59mm). Elongated gold piece with several punch marks.</p><p><br /></p><p>At this point during the Shogunate, Kobans contained about 56% gold and the 46% silver. They were originally 100% gold when created in the 1600&#039;s and were continually debased as time went on. One Ryo, or Koban, was worth about one year&#039;s worth of rice apparently, and were created as the Portuguese were not interested in trading for rice. </p><p><br /></p><p>A pretty amazing piece of history and unusual coinage. Fits well with the time period as Japanese way of life differed immensely with that of the foreigners who traded there. </p><p><br /></p><p><br /></p><p><br /></p><p>[GALLERY=media, 18561]Tempo Koban by Mrktstrtmyhm posted Nov 3, 2021 at 9:08 AM[/GALLERY][GALLERY=media, 18562]Tempo Koban by Mrktstrtmyhm posted Nov 3, 2021 at 9:08 AM[/GALLERY][GALLERY=media, 18563]Koban Presentation by Mrktstrtmyhm posted Nov 3, 2021 at 9:08 AM[/GALLERY][/QUOTE]</p><p><br /></p>
