I have most of my others idenitfied at least to the era, but this one I am troubled with, I'm thinking Early Han, but not sure stainless
You are correct. The image is actually upside-down but the coin is a ban liang. These coins were first cast by the State of Qin during the Warring States Period and then continued during the Qin Dynasty (221 BC - 207 BC) and early Western Han Dynasty (206 BC - 24 AD). For a more detailed discussion with many unusual examples please see "Ban Liang Coins". Gary
Ah k. Sweet. That's what I thought. Thanks a bunch for the info. I'll be sure to change the image to the right side up. stainless
