Any opinions on this? This was given to me years ago by a friend, but there are a few details that just seem off to me when compared to other examples I've seen online...
- The bust (Tang Jiyao) appears to have a mustache
- The obv and rev portrait edging is inconsistent in spacing (the circles)
- Denticles are different
- Flowers on the obverse are different
- Reverse side flag on the left is different
- The 11 o'clock on the obverse has a bit of a nick and it does appear to be brass or copper.
- Other details here and there as well
Dare to say that this might be a counterfeit? Variety? I'm just not versed in Chinese coinage. Any help would be appreciated.
