How did you authenticate this piece? I come across similar but also know there's lots of copies and touristy knockoffs. Peace Roy
I use auction catalogues mainly, in this case Steven Album.. The weight of this piece is within the range of Spades during this short period of Wang Mang in the Xin Dynasty. These are found in hoards or sometimes in tombs. The calligraphy is correct for the spade. The hole is very crude. These are kinda common for this time period.
Steve Album has a well respected expert on staff. Chinese coins from his firm can be trusted as authentic.
