Can anyone tell me: 1. WHAT PERIOD THIS COIN IS FROM 2. WHAT THE DENOMINATION IS? 3. WHAT IT MAY BE WORTH (BALLPARK) I see quite a few on ebay that range from 100 dollars all the way up to around 3000. The envelope states it is Japanese Gold and is in XF condition. It is 1/4 of an inch by a little over 1/8 of an inch Your feedback is very much appreciated.
The first picture is upside down. The denomination is: 二朱 or Ni Shu, or 2 Shu. It seems to match one of the following two types, though this isn't definitive: 1. 天保二朱判金 Tempo Ni Shu Ban Kin, 1832 - 1858 with mintage of 103,069,602 (29.8% gold). 2. 万延二朱判金 Man-En Ni Shu Ban Kin, 1860 - 1869 with mintage of 25,120,000 (22.9% gold). Both types are listed as "Common." I'm not sure of the value, but you could look up the type to get an idea.
