This was given to me as a gift. I was told it was real but I don't know if I believe that.
Absolutely 100% replica, I'm afraid.
A genuine 2300 year old bronze spade coin would have a thick, green patina on it. Or a horrible corroded-looking appearance after having had its think green patina removed with acid. It would not look as freshly cast as the day it was made - which is how this one looks.
