(Copper Vase)

Copper Vase

I bought this old vase at a yard sale 20+ yrs ago. It has naturally tarnished to this green/black/gold color, and has been since I have owned it. A couple years ago I noticed it had writing on bottom and cleaned it to find It has a inscription on bottom. After extensive searching of languages I have been unsuccessful at finding its origin. it measures 71/2" tall base is 412 across. Can you tell me anything about this vase or what it is worth. Thank You so much for your time.
